Calculate the average decelerating impact force if a person falling with a terminal velocity of 62.5 m/sec is decelerated to zero velocity over a distance of 1 m. Assume that the person's mass is 70 kg and that she lands flat on her back so that the area of impact is 0.3 m2. Is this force below the level for serious injury? (For body tissue, this is about 5 x 10 dyn/cm2.)
