Question

Please help me solve problem 5.2 step by step solutions.

Please explain it to me. Thank you!

**Exercise 5-1:**

Assume that a 50-kg runner trips and falls on his extended hand. If the bones of one arm absorb all the kinetic energy (neglecting the energy of the fall), what is the minimum speed of the runner that will cause a fracture of the arm bone? Assume that the length of the arm is 1 m and that the area of the bone is 4 cm².

**Exercise 5-2:**

Repeat the calculations in Exercise 5-1 using impulsive force considerations. Assume that the duration of impact is 10⁻² sec and the area of impact is 4 cm². Repeat the calculation with an area of impact = 1 cm².
