A 43.0 kg parachutist is moving straight downward with a speed
of 3.70 m/s .
If the parachutist comes to rest with constant acceleration over
a distance of 0.775 m , what force does the ground exert on
her?
Express your answer to three significant figures and include the
appropriate units.
If the parachutist comes to rest over a shorter distance, is the
force exerted by the ground greater than, less than, or the same as
in part A? Explain.
