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))

The ball is projected vertically down with a velocity of 10sqrt(3)m/s from a height of 20m .On the hitting the ground if it loses 40% of its energy the height to which it bounces is (g=10ms^(-2))

The ball is projected vertically down with a velocity of 10sqrt(3)m/s from a height of 20m .On the hitting the ground if it loses 40% of its energy the height to which it bounces is (g=10ms^(-2))

A ball is thrown vertically downwards from a height of 20 m with an initial velocity v_(0) It collides with the ground , loses 50 percent of its energy in collision and rebounds to the same height .the initial velocity v_(0) is : (Take g = 10 ms^(-2) )
