im reviewing for my final tomorrow, and there is a question that asks for the impulse experienced if a 70kg person lands on firm ground and stops after jumping from a height of 5m. what equation should i use to solve this?

$$I = \Delta p = F\Delta t$$

Where I is impulse, and p is momentum.

So impulse is a change in momentum, or the product of a force and the time period over which it acts.
