On a dare a student with a mass of 80 kg jumps from a balcony onto a trampoline (he survived by the way). After reviewing the video we measured that he was going 29.1 m/s when he hit the trampoline. The video showed he continued to stretch the trampoline 0.8 m before coming to a stop before launching him back in the air. What is the magnitude of the average force exerted on the student by the trampoline?
