Problem
A gymnast lands on a thick foam mat after performing a jump.
(a) Explain why the foam mat lowers the risk of injury compared with landing on a hard floor.
(b) If the contact time on the mat is about twice the contact time on the hard floor, how does the average force on the gymnast change? Answer qualitatively (increases / decreases / remains the same).
