A brave but inadequate rugby player is being pushed
Chapter 4, Problem 16(choose chapter or problem)
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 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 110 kg?
(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.

ANSWER:Step 1 of 4
Given data:
A brave but inadequate rugby player is being pushed backward by an opposing player exerting a force of 800 N on him. The losing player plus equipment mass is 90.0 kg, and he is accelerating at \(1.20\;{\rm{m/}}{{\rm{s}}^2}\) backwards. The player’s mass plus equipment is 110 kg.
