A family took a trip in a car traveling East from Greensboro to Wilmington, NC. Use the Graph to answer the questions below.
1: Calculate the average speed of the trip.
2: What was the average velocity of the car?
Note: Please don't put weird stuff or completely off-topic stuff, I really need help for this homework! Thanks!
Answer:
1). Average speed = 1.5 m per second
2). Average velocity = 1.5 m per second
Explanation:
1). Since, speed is a scalar quantity
Therefore, average speed of the trip = [tex]\frac{\text{Total distance covered}}{\text{Total time taken}}[/tex]
From the graph attached,
Total distance covered = 10 + 10 + 20 + 0 + 20 + 30
= 90 meters
Total time taken = 60 seconds
Average speed = [tex]\frac{90}{60}[/tex]
= 1.5 meter per second
2). Velocity is a vector quantity.
Therefore, average velocity = [tex]\frac{\triangle d}{\triangle t}[/tex]
= [tex]\frac{d_{60}-d_0}{60-0}[/tex]
= [tex]\frac{90-0}{60-0}[/tex]
= 1.5 meter per second

3. A warehouse employee is pushing a 30.0 kg desk across a floor at a
constant speed of 0.50 m/s. How much work must the employee do on
the desk to change the speed to 1.00 m/s?
Answer: The employee must do 11.2308 Joules of work
Explanation:
Work done = force × distance
But
Force = ma(mass x acceleration due to gravity)
F = 30×9.8
F = 294N
Also distance moved can be found using the equation
v² = u² +2gS
1.00 ² = 0.50²+2(9.8)S
1 =0.25+19.6S
1-0.25 =19.6S
0.75=19.6S
S=0.75/19.6
S = 0.0382m
Work done = force × distance = FS
Work done = 294 N X 0.0382m
Workdone =11.2308Nm = 11.2308 Joules
Work done required by the employee to do on the desk to change the speed to 1.00 m/s is 11.3 J.
What is work done?Work done is the force applied on a body to move it over a distance. Work done by a body can be given as,
[tex]W=Fd[/tex]
Here (F) is the magnitude of force and (d) is the distance traveled.
From the second law of motion, the force is product of mass time acceleration. Thus the above formula can be given as,
[tex]W=(ma)d[/tex]
For the gravitational acceleration, it can be written as,
[tex]W=(mg)d\\W=mgd[/tex]
The constant speed by which, the warehouse employee is pushing the desk across a floor is 0.50 m/s and the the final speed of the desk is 1 m/s.
Thus, the distance traveled by it can be find out using the third law of motion as,
[tex]v^2-u^2=2gd\\1^2-0.25^2=2\times9.8\times d\\d=0.0382\rm m[/tex]
As the mass of the desk is 30 kg and the distance moved is 0.382 meters. Thus, put the values in the above formula as,
[tex]W=30\times9.81\times0.0382\\W\cong11.3\rm J[/tex]
Thus the work done required by the employee to do on the desk to change the speed to 1.00 m/s is 11.3 J.

g The ant has traveled 10 cm horizontally and 6 cm vertically from its starting point on a twig with a slope of 0.5. If this is the only information the ant has, what function best approximates the geometry of the twig at the point the ant is on? b) The ant can use its model of the environment to plan its movements. In particular, it wants its next step to take it no higher than 0.1 cm above its current location. How far can the ant travel horizontally and still accomplish this?
Answer:
a) a right triangle, b) x = 0.167 m
Explanation:
a) It is asked to find which geometry figure describes the movement of the ant.
Let's use trigonometry with the angles measured in radians
tan θ = y / x
tan θ = 6/10
θ = tan⁻¹ 0.6
θ = 0.54 rad
this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle
b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea
x = 0.1 / tan 0.54
x = 0.1668 m
x = 0.167 m

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Un cuerpo lleva una velocidad de 122k por hora y de golpe frena reduciendo su velocidad a 50km por hora en un instante de tiempo de 4,5 segundos y la fuerza de frenado es de 1200n, ¿cual será su masa?
Answer:
La masa del objeto es 270.027 kilogramos.
Explanation:
Asumamos que el cuerpo decelera a tasa constante, entonces podemos calcularlo por medio de la siguiente ecuación cinemática:
[tex]a = \frac{v-v_{o}}{t}[/tex] (1)
Donde:
[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.
[tex]v[/tex] - Velocidad final, en metros por segundo.
[tex]t[/tex] - Tiempo, en segundos.
[tex]a[/tex] - Deceleración, en metros per segundo al cuadrado.
Si sabemos que [tex]v_{o} = 33.889\,\frac{m}{s}[/tex], [tex]v = 13.889\,\frac{m}{s}[/tex] y [tex]t = 4.5\,s[/tex], entonces la deceleración experimentada por el cuerpo es:
[tex]a = \frac{v-v_{o}}{t}[/tex]
[tex]a = -4.444\,\frac{m}{s^{2}}[/tex]
Por las Leyes de Newton, tenemos que la masa del cuerpo se calcula a partir de la siguiente expresión:
[tex]m = \frac{F}{a}[/tex] (2)
Donde:
[tex]m[/tex] - Masa, en kilogramos.
[tex]F[/tex] - Fuerza de frenado, en newtons.
Si sabemos que [tex]F = -1200\,N[/tex] y [tex]a = -4.444\,\frac{m}{s^{2}}[/tex], entonces la masa del cuerpo es:
[tex]m = \frac{F}{a}[/tex]
[tex]m = 270.027\,kg[/tex]
La masa del objeto es 270.027 kilogramos.

During construction, a crane lifts a 2,000-newton weight to the top of a 50-meter-tall building. How much power must the crane have to perform this task in 5 seconds? Use commas where appropriate and round to the nearest tenth.
watts:
kilowatts:
horsepower:
Answer:
Work is defined as force thru a distance: W = F * S
Power is defined as Work per unit time P = W / t
So we an write: P = F * S / t = 2000 N * 50 m / 5 s = 20,000 N-m/s
Since a Joule/sec is equivalent to a Watt
The power required is 20,000 Watts or 20 Kw
Also, you can convert to Hp since 1 Hp = 746 Watts

David put a plant in a black box as shown. The box also had a black lid to cover the front. David only opened the box to add water to the plant. The plant stayed in the box for 10 days. When David took the plant out of the box on the tenth day, the plant was dead. Why did the plant dead only after ten days in the box?
Answer:
the plant died because of lack of sunlight
Explanation:
A plant gets its food from the photosynthesis process, which combines CO₂ and H₂0 into carbohydrates, the two substances are in the box, but for this they need energy from sunlight.
CO₂ + H₂O + Sunlight /chlorophyll → (CH₂0)ₙ + O₂
the extra oxygen is released into the atmosphere.
Therefore the plant died because of lack of sunlight

A commercial jet liner takes off with an average acceleration of 3 g. How long does it take to reach the end of its runway which is 1524 meters away?
Answer:
The time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.
Explanation:
Given;
average acceleration of the commercial Jet liner, a = 3g = 3 x 9.8 m/s² = 29.4 m/s²
distance traveled by the commercial Jet liner, s = 1542 m
The time taken for the commercial Jet liner to reach the end of its runway is calculated as follows;
s = ut + ¹/₂at²
where;
u is the initial velocity of the commercial Jet liner = 0
s = 0 + ¹/₂at²
s = ¹/₂at²
2s = at²
[tex]t = \sqrt{\frac{2s}{a} } \\\\t = \sqrt{\frac{2 \times 1524}{29.4} } \\\\t = 10.18 \ s[/tex]
Therefore, the time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.
