Question

A Purdue football player of mass m =97.0 kg runs at a speed of vi = 8.0 m/s toward our Illini defensive line. They collide head on head, and the running player is totally stopped.

1) With their helmets on, the players collide with each other through a time t =0.48 s. Find the average force exerted on the player's head.
F =

N










2) Suppose they were playing 100 years ago, when people didn't wear helmets. Their heads would have collided within t =0.024 s. Find the average force for this time. (Explain to yourself why the helmet is so important to the player.)
F =

Explanation / Answer

F= change in momentum / time = 1616.67 N b)F=32333.33 as it is almost 20 times than prev ans.. so collision result will be severe and crack player's head
