As a rough model of the impact of walking/running, consider that half the mass of the body falls from a height of 5.33-cm onto a single foot. (During a typical stride, an adult's center-of-mass moves approximately this distance vertically). Use the kinematic equations to calculate the speed of an object falling from this height at the moment of impact with the ground under the influence of gravity.
