In this problem we consider the implication of size when it comes to falling. The maximum compressive strength of bone is 130x10⁶ N/m². If an adult male, with a mass of 80kg, was to jump off a five-story building and land standing straight up on both legs, would he break his leg? A typical bone cross sectional area is 3.6 x 10^-4 m² for a human and 1.8 x 10^-6 m² for a mouse. You can presume that a story is 10 ft high and that the time it took to stop, once the feet made contact with the pavement was 0.01s. If a mouse which is made of mostly the same material, but scaled down so that it weight 0.035 kg, was to fall through the same distance, would the mouse break a leg?

We didn't learn momentum or kinetic & potential energy yet, so this will require using only kinematics and newton's law.
