At the end of a run Sam (116kg) crashes into a 85kg blood-rider who was running in the wrong direction (exactly opposite of Sam) on the track at 7.2 m/s. During the collision Sam exerts and average force of 3650N on the blood-rider. Sam was traveling 4.2 m/s as he slowed down after the run. a) how big is the average force the blood rider exerts against Sam during the collision? B) if this is the only horizontal force acting on each during the collision, what average horizontal acceleration does each experience during the collision? c) if the collision is perfectly ineleastic, how fast and in what direction will Sam and the blood rider be moving immediately after the collision?

Question
At the end of a run Sam (116kg) crashes into a 85kg blood-rider who was running in the wrong direction (exactly opposite of Sam) on the track at 7.2 m/s. During the collision Sam exerts and average force of 3650N on the blood-rider. Sam was traveling 4.2 m/s as he slowed down after the run.
a) how big is the average force the blood rider exerts against Sam during the collision?
B) if this is the only horizontal force acting on each during the collision, what average horizontal acceleration does each experience during the collision?
c) if the collision is perfectly ineleastic, how fast and in what direction will Sam and the blood rider be moving immediately after the collision?
