1. The problem statement, all variables and given/known data A person jumps from the roof of a house 3.4 meters high. When he strikes the ground below, he bends his knees so that his torso decelerates over an approximate distance of 0.70 meters. If the mass of his torso (excluding legs) is 41 kg. A. Find his velocity just before his feet strike the ground. B. Find the average force exerted on his torso by his legs during deceleration. 2. Relevant equations I can't even seem to figure that part out. Help please? 3. The attempt at a solution I don't know how to start this at all
I need help on this too lol
D, which is around the speed of light
Clues or evidence
Im pretty sure its evidence though
Answer:
2666.7 N/m
Explanation:
Spring constant = force / displacement
k = F / x
k = 400 N / 0.15 m
k = 2666.7 N/m
