Hello, I have a physics question. Thanks in advance :) Question: To escape a burning building, Arnold has to jump from a third-story window that is about 10.0 m above the ground. Arnold is worried about breaking his leg. The largest bone in Arnold’s leg is the femur, which has a minimum cross-sectional area of about 5.00 × 10−4 m. Arnold has a mass of 93.0 kg. If Arnold lands on the ground with his legs stiff, and if his femur can compress only about 5.00 mm, what is the compressive stress on each femur? If Arnold lands in deep snow, then his legs can move about 30.0 cm between the time they first hit the snow and the time he comes to a complete stop. What is the compressive stress on each femur?
