A person pushing a uniformly-loaded 51.2 kg wheelbarrow of length L with pushing force P is attempting to get it over a step. The maximum horizontal force that the person can apply is P, = 649 N. What is the maximum height h of the step, expressed as a fraction n of the wheel's radius R, that the person can get the wheelbarrow over? The gravitational acceleration is g = 9.81 m/s². R h = h = nR
