Momentum

A 75kg skater moving at 10m/s crashes into a stationary skater of equal mass. After the collision, the two skaters move as a unit of 5m/s. Suppose the average force of the skater experience without breaking a bone is 4500 newton. If the impact time is 0.100 seconds, does a bone break?
Question asked by: jacquelyn

Asked on: 24 Sep 2008

Whether a bone is broken doesn't really depend so much on momentum as to what bone is being hit and what angle etc.

Therefore this question has no answer!
