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 vehicle is accelerating on a straight road. Its velocity at any instant is 30 km h^-1, after 2 s, it is 33.6 km h^-1 and after further 2 s, it is 37.2 km h^-1. Find the acceleration of vehicle in m s^-2. Is the acceleration uniform ?

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

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