A ball falls under gravity from a hight of 10 m height of 10 m wioth an initial downward velocity u .If collides with the gound , loses `50%` of its energy in collision and then rises back back to the same heighrt .Find the initial velocity u.

A ball falls under gravity from a height of 10m with an initial downward velocity u. It collides with the ground, loses 50% of its energy in collision and then rises back to the same height. Find the initial velocity ''u''.
