Question 1 During a rugby game two players are running toward each other. One has a mass of 75.0 kg and the other has a mass of 56.9 kg. The player who has the bigger mass is running at 1.90 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? :l Question 2 m A 4.50 kg box sits halfway up a 10.0 m long ramp that is inclined at an angle of 16.00. You shove a second box, of mass 3.00 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 16.5 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.150. Where, from the bottom of the ramp, do they come to rest? :l
