Question

Please help me solve problem 5.2 step by step solutions.

Please explain it to me. Thank you!

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 frac-
ture of the arm bone? Assume that the length of arm is 1 m and that the
area of the bone is 4 cm?.
5-2 Repeat the calculations in Exercise 5-1 using impulsive force consider-
ations. Assume that the duration of impact is 10-2sec and the area of
impact is 4 cm2. Repeat the calculation with area of impact = 1 cm?.
