Question

(0) A ball falls under gravity from a height of 10m with an initial downward velocity V_(0) .If collides with the ground loses 50% of its energy in collision and then rises back to the same height.Find (i) the initial velocity vo and (ii) the height to which the ball would rise after collision if the initial velocity was directed Upward instead of downward.​

Answer 1

2 point is right because the the height to which the ball would rise after collision if the initial velocity was directed Upward instead of downward.
