Question

During a rugby game, two players are running toward each other. One has a mass of 88.3 kg and the other has a mass of 55.4 kg. The player who has the bigger mass is running at 1.50 m/s and the other is running at 4.90 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 0.400, how far did they slide?
