A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.
<h3>What is Uniformly Accelerated Motion?</h3>
Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.
A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.
v² = u² + 2 × a × s
v² = (0 m/s)² + 2 × (9 m/s²) × 240 m
v = 66 m/s
where,
- v is the final speed.
- u is the initial speed.
- a is the acceleration.
- s is the displacement.

A mechanical wave such as sound needs a medium to travel through. This is why they say that in space, no one can hear you scream (because space is a vacuum and no medium exists). On the contrary, light can exist in wave or particle form. This is why we have the ability to see beyond the realms of the Earth.
Answer:
The increase in gravitational potential energy is the same in both cases
Explanation:
It is easier to climb a mountain in a zigzag way rather than climbing on a straight line but since the distance is the same ( vertical height ) , mass and gravity is the same. Hence the increase in gravitational potential energy is the same in both cases.
gravitational potential energy = mgh ( same in both cases )
m = mass
g = acceleration due to gravity
h = distance ( vertical height )
Answer:
W= 210 N
Explanation:
Just use work = Fparallel*d
W= 35*6
W= 210 N
