During the game of table tennis, if the ball hits a player, it does not hurt him. However, if a fast moving cricket ball hits a spectator, it might hurt him. State reason.

  Force of impact will depend on the rate of change of momentum. So for a fast moving ball will have more velocity thus have more momentum and will have more impact than the slow moving ball.
