Answer 1

Answer:

Jumping from greater height means that you achieve higher velocity before landing, hence there is a larger downward momentum at the time of landing. The moment the person lands, the momentum has to change to zero in an instant. ... This is the reason why we hurt ourselves when we jump from a higher height.

Hope it helps.
