Find what initial speed should the ball have

Reference no: EM13664200

A person throw directly downward an ideally elastic ball from the height 4.20 meter. The ball is being bounced from the ground reaching certain (unknown) height h. Neglect air resistance.

If the initial speed of the ball is 3.4 m/s, determine the speed when it hits the ground?

Find what initial speed should the ball have in order to bounce to the level of 7.00 meter above the ground?
