A football player kicks a ball with an initial velocity of 30 meters per second at an angle of 53° above the horizontal. how long will the ball be in the air for
At time t, the ball attains a height y of
y = (30 m/s) sin(53º) t - 1/2 g t²
where g = 9.80 m/s² is the magnitude of the acceleration due to gravity.
Solve for t when y = 0:
(30 m/s) sin(53º) t - 1/2 g t² = 0
t ((30 m/s) sin(53º) - (4.90 m/s²) t ) = 0
t = 0 or (30 m/s) sin(53º) - (4.90 m/s²) t = 0
We ignore the first solution, since that refers to the moment the ball is kicked.
(30 m/s) sin(53º) - (4.90 m/s²) t = 0
(30 m/s) sin(53º) = (4.90 m/s²) t
t = (30 m/s) sin(53º) / (4.90 m/s²)
t ≈ 4.9 s

Explanation:
a box is at rest and a force of 250N is applied to it.If the frictional force is 200N determine the net force
Answer:
50N
Explanation:
the net force is the addition of all forces in an object.
The frictional force is the opposite of the applied force, so:
Nf(net force)= 250(applied force)-200(frictional force)
so Nf=50N

Explanation:
(1). Given that,
Initial position = 0 m
Average speed = 0.50 m/s
Time = 3.0 s
We need to calculate the final position
Using formula of average speed
[tex]v_{av}=\dfrac{x_{f}+x_{i}}{t}[/tex]
Where, [tex]x_{f}[/tex] = final position
[tex]x_{i}[/tex] = Initial position
t = total time
Put the value into the formula
[tex]0.50=\dfrac{x_{f}+0}{3.0}[/tex]
[tex]x_{f}=0.50\times3.0[/tex]
[tex]x_{f}=1.5\ m[/tex]
(2). Given that,
Initial position = 0 m
Average speed = 0.75 m/s
Time = 4.0 s
We need to calculate the final position
Using formula of average speed

Put the value into the formula
[tex]0.75=\dfrac{x_{f}+0}{4.0}[/tex]
[tex]x_{f}=0.75\times4.0[/tex]
[tex]x_{f}=3\ m[/tex]
(3). Given that,
Average speed = 1.25 m/s
Time = 3.0 sec
Initial position = 1.0 m
We need to calculate the final position
Using formula of average speed
[tex]v=\dfrac{x_{f}+x_{i}}{t}[/tex]
Put the value into the formula
[tex]1.25=\dfrac{x_{f}+1.0}{3.0}[/tex]
[tex]x_{f}=1.25\times3.0-1.0[/tex]
[tex]x_{f}=2.75\ m[/tex]
(4). Given that,
Average speed = 1.25 m/s
Distance = 100 m
We need to calculate the time
Using formula of time
[tex]t=\dfrac{d}{v}[/tex]
Put the value into the formula
[tex]t=\dfrac{100}{1.25}[/tex]
[tex]t=80 sec[/tex]

Average speed = 5 miles/hr
Suppose, distance = 25 miles
We need to calculate the time
Using formula of time
[tex]t=\dfrac{d}{v}[/tex]
Put the value into the formula
[tex]t=\dfrac{25}{5}[/tex]
[tex]t=5\ hr[/tex]
Hence, (1). His final position is 1.5 m.

Gravity causes objects to be attracted to one another. This attraction keeps our feet firmly planted on the ground and causes the moon to orbit the earth. The force of gravitational attraction is represented by the equation F=Gm1m2r2, where F is the magnitude of the gravitational attraction on either body, m1 and m2 are the masses of the bodies, rrr is the distance between them, and G is the gravitational constant. In SI units, the units of force are kg⋅m/s2, the units of mass are kg, and the units of distance are mm. For this equation to have consistent units, the units of G must be which of the following?
A. kg3m⋅s2
B. kg⋅s2m3
C. m3kg⋅s2
D. mkg⋅s2
Answer:
C m³/kgs²
Explanation:
From the question, we know that
F = Gm1m2/R², where
F = the Force of gravity in N.
G = gravitational constant, in Nm²/kg²
m1 = mass in kg
m2 = mass in kg
R = distance between the objects in m
Now, if we substitute the units of each in the formula, we have
N = G * (kg * kg) / m²
N = G (kg²) / m²
Nm² = G kg², remember, N itself is kgm/s², so we substitute for that
Kgm/s² * m² = G kg²
Kgm³/s² = G kg²
G = (kgm³/s²) / kg²
G = m³/kgs²
And that's our answer
The integral with respect to time of a force applied to an object is a measure called impulse, and the impulse applied to an object during a time interval determines its change in momentum during the time interval. The safety of a t-shirt launcher, used to help get crowds cheering at baseball games, is being evaluated. As a first step in the evaluation, engineers consider the design momentum of the launched t-shirts. The springs in the launcher are designed to apply a variable force to a t-shirt over a time interval of t1 = 0.5 s. The force as a function of time is given by F(t) = ať+ b, where a = –28 N/s2 and b = 7.0 N. The momentum of the t-shirt will be its initial momentum (po 0) plus its change in momentum due to the applied impulse: pf = po+SET+ F(t) dt. By applying the given time dependent function for F(t) and performing the integration, which of the following is the correct expression for Pf?
a) tl tl Pf= 0++)16
b) 0+*+*+b)
c) 0+++bt) 0++) ti
Answer:
Follows are the solution to this question:
Explanation:
By checking the value in which we have calculated by performing its differentiation of [tex]\frac{a}{3}t^3+bt[/tex], the correct form of its integer value is calculating with regard to t, that also provides as expected [tex]at^2+b = F(t)[/tex].

Explanation:
Students are studying the two-dimensional motion of objects as they move through the air. Specifically, they are examining the behavior of a sphere that is launched horizontally from a location above the floor with an initial velocity vo in the +3 direction, as shown in the figure. The students assume that the positive directions are along the sphere's initial velocity for horizontal motion and downward for vertical motion.
The horizontal displacement of the object from its starting point is x, and the vertical displacement of the object from its starting point is y. One of the students derives an equation for y in terms of xx and other quantities. After examining the equation, the student claims that y is proportional to x^2.
Required:
Derive an equation for the vertical coordinate y of the sphere as a function of x, v0, and physical constants, as appropriate.
Answer:
y = - (½ g / v₀²) x²
Explanation:
This is a projectile launch exercise where there is no acceleration on the x-axis so
x = v₀ₓ t
v₀ₓ = v₀ cos tea
y = [tex]v_{oy}[/tex] t - ½ g t2
v_{oy} = v₀ sin θ
as the sphere is thrown horizontally, the angle is tea = 0º, so the initial velocity remains
v₀ₓ = v₀
v_{oy} = 0
we substitute in our equations
x = v₀ t
y = - ½ g t²
we eliminate the time from these equations, we substitute the first in the second
y = - ½ g (x / v₀)²
y = - (½ g / v₀²) x²
this is the equation of a parabola

While making some observations at the top of the 63 m tall Astronomy tower, Ron
accidently knocks a 0.5 kg stone over the edge. How fast will the stone be moving when
it hits the ground?
Analysing the Question:
We are given:
height of the tower (h) = 63 m
mass of stone (m) = 0.5 kg
initial vertical velocity of the stone (u) = 0 m/s [ since the stone fell, there was no force applied on it to go downwards]
final vertical velocity of the stone (v) = v m/s
acceleration of the stone due to gravity (a) = 10 m/s² [we are letting g = 10]
** We will be neglecting air resistance in this answer**
Finding the final velocity of the stone:
from the third equation of motion
v² - u² = 2ah
replacing the variables
v² - (0)² = 2(10)(63)
v² = 1260
v = √1260
v = 35.5 m/s

A car goes from 80 kn/h to 20 km/h in 0.5 h. What is the acceleration in km/h^2? *
Answer:
In physics, acceleration is defined as the rate of change of the velocity of an object with respect to time. That is A = VF - VI /T; Where A = Acceleration VF = Final velocity = 20 km VI = Initial velocity = 80 km T= Time = 0.5 hr A = (20 - 80)/ 0.5 = - 60/.5 A = - 120 Km/ hr^2 Therefore, the acceleration of the car is -120 km/hr^2. Because the value is negative, the appropriate name that describe it is deceleration.I Hope this helps

Given the vector A with components Ax = 2.00, Ay = 6.00, the vector B with components Bx = 2.00, By = 22.00, and the vector D = A - B, calculate the magnitude and angel with the x axis of the vector D
Answer:
The magnitude of vector d is 16 and the angle with the x-axis is 270°
Explanation:
Operations With Vectors
Given two vectors in rectangular components:
[tex]\vec a=(ax,ay)\ ,\ \vec b=(bx,by)[/tex]
The sum of the vectors is:
[tex]\vec a+\vec b=(ax+bx,ay+by)[/tex]
The difference between the vectors is:
[tex]\vec a-\vec b=(ax-bx,ay-by)[/tex]
The magnitude of [tex]\vec a[/tex] is:
[tex]|\vec a|=\sqrt{ax^2+ay^2}[/tex]
The angle [tex]\vec a[/tex] makes with the horizontal positive direction is:
[tex]\displaystyle \tan\theta=\frac{ay}{ax}\\[/tex]
The question provides the vectors:
[tex]\vec a=(2,6)[/tex]
[tex]\vec b=(2,22)[/tex]
[tex]\vec d=\vec a-\vec b[/tex]
Calculate:
[tex]\vec d=(2,6)-(2,22)=(0,-16)[/tex]
The magnitude of [tex]\vec d[/tex] is:
[tex]|\vec d|=\sqrt{0^2+(-16)^2}=\sqrt{0+256}=16[/tex]
The angle is calculated by:
[tex]\displaystyle \tan\theta=\frac{-16}{0}[/tex]
The division cannot be calculated because the denominator is zero. We need to estimate the correct angle by looking at the components of the vector. Since the x-coordinate is zero and the y-coordinate is negative, the vector points downwards (south), thus the angle must be -90° or 270° if the range goes from 0° to 360°.
The magnitude of vector d is 16 and the angle with the x-axis is 270°
