A body initially at rest travels a distance 100 m in 5 s with a constant acceleration. Find the acceleration.

A body starts from rest with a uniform acceleration $$2 m s^{-2}$$. Find the distance covered by the body in $$2\  s$$.

Figure shows displacement-time graph of two vehicles A and B moving along a straight road. Which vehicle is moving faster?

A bullet initially moving with a velocity $$20\ ms^{-1}$$ strikes a target and comes to rest after penetrating a distance 10 m in the target. Calculate the retardation caused by the target.

A body starts with an initial velocity of $$10 m s^{-1}$$ and acceleration $$5 m s^{-2}$$. Find the distance covered by it in $$5\  s$$.

A train moving with a velocity of $$20\ ms^{-1}$$ is brought to rest by applying the brakes in 5 s. Calculate the retardation.

A toy car, initially moving with a uniform velocity of $$18 \ km h^{-1}$$ comes to rest in $$2\ s$$. Find the retardation of the car in S.I units.

The expression for the displacement $$s$$ covered  in time $$t$$ by a body which is initially at rest and starts moving with a constant acceleration $$a$$ is:

A body initially at rest starts moving with a constant acceleration $$2\ ms^{-2}$$. Calculate the distance traveled in 5 s.
