Answer:
water filtration
Explanation:
In the case of a mixture of sand and water filtration can used to separate the two. This requires a sieve that does not allow any of the particles of sand to pass through.
An object moving north with an initial velocity of 14 m/s accelerates 5 m/s^2 for 20 seconds.what is the final velocity of the object?
39 m/s
90 m/s
114 m/s
414m/s
Answer:
Option C = 114 m/s
Explanation:
a=v-u/t
By substituting,
5=v-14/20
100=v-14
Thus, v=100+14
v= 114 m/s

A truck loaded with sand accelerates at 0.5 m/s2 on the highway. If the driving force on the truck remains constant, what happens to the truck’s acceleration if sand leaks at a constant rate from a hole in the truck bed?
Answer:
It will accelerate at a constant rate.
Explanation:
If the driving force is constant, with a constant reduction in weight, the truck will accelerate at a constant rate.
the acceleration of the truck increase if sand leaks at a constant rate from a hole in the truck bed.
What is Newton's second law of motion ?Force(F) applied on the body is mass(m) times its acceleration(a). i.e. F=ma according to this equation we get acceleration as a = F/m this equation says that when we apply more force to the body, more acceleration it gets. When more is the mass of the body, greater force is needed to accelerate with same amount to that less mass.
According to the relation, a = F/m
mass produces inertia in the body, means mass is a resistance to the linear motion. if mass is greater acceleration is less and mass is more the acceleration is more.
if mass sand leaks at a constant rate from a hole in the truck bed, mass of the truck decreases which increases the acceleration.

If a car starts from rest and accelerates at 4 m/s2 for 8 sec, how far did it travel
Answer:
128 m
Explanation:
S = ut + [tex]\frac{1}{2}[/tex]a[tex]t^{2}[/tex]
where u= initial velocity
S= (0×2s) + ( [tex]\frac{1}{2}[/tex]×4[tex]\frac{m}{s^{2} }[/tex]×(8s)

Two friends push a stalled
1330 kg car with a 187 N force,
How much time does it take
to move the car 5.00 m?
(Unit = s)
Answer:
8.42s
Explanation:
The time (in seconds) needed to move the car can be calculated using the formula:
S = ut + 1/2at²
Where; S = distance (m) = 5m
u = initial velocity (m/s)
a = acceleration (m/s²)
t = time (s)
However, the acceleration (a) can be got by using F = ma
Where; F = force = 187 N
m = mass = 1330 kg
F = ma
a = F/m
a = 187/1330
a = 0.1406
a = 0.141m/s²
Since a= 0.141m/s², S = 5m, t =
S = ut + 1/2at²
5 = (0 × t) + 1/2 × (0.141 × t²)
5 = 0 + 0.141t²/2
5 = 0.141t²/2
10 = 0.141t²
t² = 10/0.141
t² = 70.922
t = √70.922
t = 8.42s

A car traveling at 7 m/s accelerates at 2,5 m/s2 to reach a speed of 12 m/s. How long
does it take for this acceleration?
Answer:
The car took 2.5 seconds for this acceleration
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at[/tex]
Solving for t:
[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]
The car was traveling at v0=7 m/s, accelerated at 2.5 m/s^2, and reached a speed vf=12 m/s. Calculating the time taken:
[tex]\displaystyle t=\frac{12-7}{2.5}[/tex]
[tex]\displaystyle t=\frac{5}{2.5}[/tex]
t=2 sec
The car took 2 seconds for this acceleration

Gravitational Force
Normal Force
Friction Force
Tension Force
Spring Force
what is situation where all forces are involved ?
Explanation:
Gravitational force
The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself.
Normal force
The normal force is the support force exerted upon an object that is in contact with another stable object.
Friction force
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it.
Tension force
The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends.
Spring force
The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it.
