Question

5. 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 1.20m/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 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 1

Losing player ازيا winning player 9 Refer to the free body diagram of the loosing player and write equabian of motian accarding to Mewtainyo 2nd 20w. Foining I - Front I = Fainning - Frete F = Fuinning -mă F = 800 - 90x1-2 =( 692 ^] frichten farce applied by the Losing player an the gress = 6922. (6 frickan farce for both the player as same and write expressian far het farce for the winning player Frost -f2 = Fretz Ffoot = maath Front = 110X1-2 +692 = (824M fance applied by winning player an the ground = 824m
