A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 N on him. The mass of the losing player plus equipment is 90.0 Kg, and he is accelerating at 1.20 m/s2 backward. a) What is the force friction between losing player's feet and grass? b) What force does the winning player exert on the ground to move forward if his mass plus equipment is 110Kg? 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.
