A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 820N on him. The mass of the losing plater plus equipment is 93.0kg and he is accelerating at 1.20m/s² backward. a.) What is the force of friction between the losing player's feet and the grass?

b.) What force does the winning player exert on the ground to move forward if his mass plus equipment is 112kg?

c.) Draw a sketch of the situation showing the system of interest used to solve each part. For this situation, draw a free-body diagram and write the net force equation.
