After clearing the bar on a high jump, you land softly on a giant mattress. landing on a mattress is 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.
b. the force the mattress exerts on you to stop your descend is much less than the force the sand heap would exert on you.
c. you transfer less energy to the mattress in coming to a stop than you would have transferred to the sand heap.
d. you transfer more momentum to the mattress in coming to a stop than you would have transferred to the sand heap.
e. your velocity is less as you land on the mattress than it would be if you landed on the sand heap.
