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

A car accelerates at a rate of 5 m s^-2. Find the increase in its velocity in 2 s.

A bicycle initially moving with a velocity 5.0 m s ^-1 accelerates for 5 s at a rate of 2 m s^-2 . What will be its final velocity?

A car is moving in a straight line with speed 18 km h^-1. It is stopped in 5s by applying the brakes.

Find —

(i) the speed of car in m s ^-1,

(ii) the retardation and

(iii) the speed of car after 2 s of applying the brakes .
