A car moving with a velocity of 72 KMPH stops its engine just at the foot of a hill. If the car ascends a height of 12m, the energy lost in overcoming friction is (g = 10 m//s^(-2))

A car is travelling at 36 kmph on a road. If mu=0.5 between the tyres and the road, the minimum turning radius of the car is: ( g = 10 ms^(-2) )

A ball is projected vertically down with an initial velocity from a height of 20m on to a horizontal floor. During the impact it loses 50% of its energy and rebounds to the same height. The velocity of projection is (g=10ms^(-2))
