In Fig. 12-28, a man is trying to get his car out of mud on the shoulder of a road. He ties one end of a rope tightly around the front bumper and the other end tightly around a utility pole 28 m away. He then pushes sideways on the rope at its midpoint with a force of 500 N, displacing the center of the rope 0.21 m from its previous position, and the car barely moves. What is the magnitude of the force on the car from the rope? (The rope stretches somewhat.)
