A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 740 N on him. The mass of the losing player plus equipment is 88 kg, and he is accelerating at 1.8 m/s2 backward. f = 740 Nm1 = 88 kgm2 = 118 kga = 1.8 m/s2 1. What is the magnitude of the force of friction, in newtons, between the losing player's feet and the grass as he slides backwards? F1= 2. What is the magnitude of the force, in newtons, that the winning player exerts on the ground to move forward if his mass plus equipment is 118 kg? Assume the second player has the same acceleration as the first. F2=

A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 781 N, overcoming the force of friction between the losing player’s feet and the grass.The mass of the losing player plus equipment is 80.1 kg. The losing player is accelerating at 1.22 m/s² backward. What is the magnitude of the force of friction between the losing player’s feet and the grass?To solve this problem, draw a free-body diagram for the losing player. Then write the equation for the net force and acceleration in the horizontal direction, using variables for any unknowns. Finally, solvefor the force of friction, and calculate the magnitude of the force of friction on the losing player.

A car has a mass of 1750 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 6500 N. If the car is moving at 22 m/s, what is the shortest distance in which the car can stop safely?
A 68.5 kg person is standing inside an elevator. The elevator is going from the 1st floor to the 9th floor. As the elevator approaches the 9th floor there is a moment when the elevator’s speed is 2.90 m/s and is slowing at a rate of 0.904 m/s2. What is the net force acting on the person at this moment?
Alex is asked to move two boxes of books in contact with each other and resting on a frictionless floor. He decides to move them at the same time by pushing on box A with a horizontal pushing force p =7.5N. Box A has a mass = 10.5 kg and box B has a mass 7.0 kg. The contact force between the two boxes is F and N denotes the normal force. A) What is the acceleration (in m/s to the 2nd) of the two boxes B) What is the force (in N) exerted on mb by ma? C) If Alex were to push from the other side on the 7.0 kg box, how would your answer to part (b) change?

During your winter break, you enter a sled race. You push the sled with a force of 210 N at 30.0° below the horizontal as shown. The mass of the sled (and your nephew sitting on it) is 35.0 kg. The coefficients of friction between the sled and icy surface are us = 0.35 and uk = 0.20. What is the magnitude of the acceleration of the sled, in m/s2? Use g = 10.0 m/s?. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
