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.

Answer:

The right approach is Option b (the force..................exert on you).

Step-by-step explanation:

  • Even before you fall on something like a soft object, users eventually slow to a halt. You are still giving away all the downward momentum, but progressively although with small powers, you are doing so.
  • Although you can get injured by massive powers, this gradual displacement is a positive thing. And that is why you have a mattress you would like to settle on.

The other options given are not connected to the situation described. So, the solution here was the right one.
