Impact Force

The impact on a human body can be difficult to determine since it depends on how the body hits the ground - which part of the body the angle of the body and/or if hands are used to protect the body and so on For this example we use an impact distance of 3/4 inch 00625 ft to calculate the impact force F avg = 800 ft lb / 00625 ft...
