The football season is beginning with mixed results for the Browns. Let's analyze a tackle in which player A is being pushed backwards by opposing player B who is exerting a force of 900. N on him. The mass of the player A (plus equipment) is 100 kg, and he is accelerating backwards at 1.2 m/s². The mass of player B (plus equipment) is 110 kg. a. Draw separate free body diagrams for player A and for player B. b. Determine the force of friction between player B's feet and the grass. C. Determine the force of friction between player A's feet and the grass.
