Rolling on the ground after a jump protects your bones by extending the:
ASpeed of landing
BTime the force acts
CHeight of the jump
DMass of your body
Answer & Solution
Correct answer: B. Time the force acts
1. Landing stiff-legged gives a huge force.
2. Rolling spreads the stop over more time.
3. Parachutists do the same.
