... (b) If the parachutist comes to rest in a shorter distance, the acceleration will be greater so the net force will be greater, so the force of the ground on the parachutist will therefore be greater. You must provide an equation that shows acceleration’s dependence on stopping distance. (a) = 5146 ...
