Unformatted text preview: reddy (ar38357) 2D Equilibrium clancy (SCI411-2) 1 This print-out should have 5 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points A student gets her car stuck in a snow drift. Not at a loss, having studied physics, she attaches one end of a rope to the vehicle and the other end to the trunk of a nearby tree, allowing for a small amount of slack. The student then exerts a force F on the center of the rope in the direction perpendicular to the car-tree line as shown. Assume equilibrium conditions and that the rope is inextensible. L d F How does the magnitude of the force ex- erted by the rope on the car compare to that of the force exerted by the rope on the tree? 1. Cannot be determined 2. | F t | > | F c | 3. | F t | < | F c | 4. | F t | = | F c | = T correct 5. | F t | = 2 | F c | Explanation: Since the the student pulls on the center of the rope, the angle between the rope and the...
