A ball is thrown down with an initial velocity v_0 from a height of 10m. The ball lost 50% of its energy on coming in contact with the ground , and then bouncing back up tothe same height. Find v_0 of the ball. If theinitial velocity was upward instead of downward, up to what height would the ball have bounced ?
