A ball is projected vertically down with an initial velocity from a height of `20 m` onto a horizontal floor. During the impact it loses `50%` of its energy and rebounds to the same height. The initial velocity of its projection is

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))

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