ok my physics class jst did a lab on studying rebound and last question in the report says: An extrapolation of the data to a perfect bounce (ie. one that reaches to the height of the launch point) results in a bounce distance that is more than twice the horizontal distance of the point of impact from the launch point. Since the fall of the ball from the launch point is only half the trajectory of such a perfect bounce, this means that the horizontal velocity after the bounce is greater than it was before the bounce. What is a possible reason for this?? i am stuck on this last question...ne help would be much appreciated!
