You drop a 750g basketball out of your hand from rest. The basketball falls down a distance of 2.8m before striking the ground. Solve for the velocity that the basketball strikes the ground with. (assume this is an elastic collision) As the basketball strikes the ground, you hold your hand at 1.7m from the ground. A human hand is 43.-0g. When the basketball bounces back up and colloids with your still hand, you allow your hand to move up with the basketball so they have the same final velocity. If 16% of the initial energy is lost in this collision. find the final height that your hand and the basketball are moved up to.
