1.During a rugby game two players are running toward each other. One has a mass of 83.1 kg and the other has a mass of 63.3 kg. The player who has the bigger mass is running at 2.00 m/s and the other is running at 4.60 m/s. They hit each other, fall to the ground and slide while attached to each other. If the coefficient of kinetic friction between the players and the ground is 0.200, how far did they slide?
2. Two identical ping pong balls are rolling toward each other. Ball one is shot to the east at a speed of 1.10 m/s and ball two is shot to the west at 4.50 m/s. They do not hit head on but have a glancing collision that deflects ball two by 90. Ball two is now moving to the north at 1.54 m/s. What is the speed of ball one after the collision?
