Returning from a rainy hike in the woods, you find that your car is now stuck in mud. Youdecide to free your car using your knowledge of physics and tie a rope to the car and then to a tree trunk about 20.0 meters from the car. You stand in the middle of the rope and push as hard as you can (exerting a force of 1,500. Newtons) on the rope in the direction perpendicular to the rope. This causes the rope to displace by 50.0 centimeters in the direction of your push. How hard is the rope pulling on your car?
