Suppose your car was mired deeply in the mud and you wanted to use the method illustrated in the figure below to pull it out. T то Tree Trunk What force would you have to exert perpendicular to the center of a rope to produce a force of 15,000 N on the car if the angle is 8 = 1.10°? (Enter the magnitude only.) 57.6 X What is the net force in the perpendicular direction? N Real ropes stretch under such forces. What force would be exerted on the car if the angle increases to 7.00° and you still apply the force found in part (a) to its center?
