Problem 33P
The maximum energy a bone can absorb without breaking is surprisingly small. Experimental data show that the leg bones of a healthy, 60 kg human can absorb about 200 J.
a. From what maximum height could a 60 kg person jump and land rigidly upright on both feet without breaking bis legs? Assume that all energy is absorbed by the leg bones in a rigid landing.
b. People jump safely from much greater heights than this. Explain how this is possible.

b. People jump safely from much greater heights than this. Explain how this is possible.
ANSWER:
Step 1 of 3
In this question, we need to find maximum a person can jump such that he lands safely without breaking his legs
In part b, we need to explain how can people jump safely much higher heights
Data given
Mass of person
Energy absorbed
