its velocity decreases at the rate of 0.05 m/s’ (acceleration,-0.05 m/s'). How much time will it take
for the body to stop.
7. A scooter moving at a speed of 20 m/s is stopped by applying brakes which produce a uniform
acceleration of, -0.5 m/s². How much distance will be covered by the scooter before it stops.
