A82.2 kg ice skater, moving at 9.1 m/s, crashes into a stationary skater of equal mass. after the collision, the two skaters move as a unit at 4.55 m/s. suppose the average force a skater can experience without breaking a bone is 4472 n. if the impact time is 0.138 s, what is the magnitude of the average force each skater experiences?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
