The racquet can really hurt a tennis ball and not just it. See for example Youzhny, PhD scientific experiment around 0:40.

Kid experiment in video (not scientific?),, shows that ball bounce high is not directly proportional drop high. The physic low is: The greater the height of the incident ball, the less the efficiency rebound (more damage).
