... Figure (a) shows velocity as downward, so the object is moving down. The length of the vector increases with each step showing that the speed is increasing (like a dropped ball). Thus, the acceleration is directed down. Since F ma the force is in the same direction as the acceleration and must be ...

... (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 ...
