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

A car is moving with a velocity 20 m s ^-1 . The brakes are applied to retard it at a rate of 2 m s ^-2. What will be the velocity after 5 s of applying the brakes ?

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 .

The slope of displacement-time graph gives:

1. Velocity
2. Acceleration
3. Speed
4. Displacement
