Answer
  • The mat or the sand bed squashes when the athlete lands on it.
  • So the velocity of the athlete falls to zero over a longer time.
  • More time to change the velocity means a smaller acceleration.
  • By F = ma, a smaller acceleration means a smaller force on the athlete.
  • That is why the landing does not injure the athlete.
