After clearing the bar in the high jump, you land softly on a giant mattress. Landing on the mattress is much more comfortable than landing on a sand heap of equal size because
A. you transfer less momentum to the mattress in coming to a stop than you would have transferred to the sand heap in coming to a stop.
B. the force that the mattress exerts on you to stop your descent is much less than the force that the sand heap would have exerted on you.
C. you transfer more momentum to the mattress in coming to a stop than you would have transferred to the sand heap in coming to a stop.
D. your velocity is less as you land on the mattress than it would have been if you'd landed on the sand heap.
