Why is it that when a man jumps down from a height of several storeys into a stretched trapaulin, he receives no injury?

Answer:

                When the man jumps, the trapaulin gets depressed at the place of impact. This increases the time of impact \[(\Delta t)\]. As a result, the trapaulin exerts a very small force (F = impulse/time) on the man, and he receives no injury.
