A running back (RB) of mass m1 = 98 kg is running at v1= (8.1m/s)ĵ LB towards the end zone. A linebacker (LB) of mass m2 = 111 kg runs at y2=(7,7m/s)î to make the tackle. The linebacker tackles the running back and together, they slide across the grass and come to a stop. (RB d) Suppose a friction force causes the two players slide to rest over a distance of Ar = 2.5 m. Using numbers, calculate a value for the magnitude of the friction force that brought them to rest. e) Using numbers, calculate a value for the coefficient of friction between the players and the grass.
