Your car is stuck in a mud hole. You are alone, but you have a long, stong rope. Having studied physics, you tie the rope tautly to a telephone pole and pull on it sideways.
a) Find the force exerted by the rope on the car, when the angle theta is 3 degrees, and you are pulling with a force of 400, but the car does not move.
b) How strong must the rope be if it takes a force of 600N on your part to move the car when theta is 4 degrees?
