P1112 Fall 2008 Homework #5 Reading: 4.3-4.6, 5.1, 5.2 Not all concepts will be covered in class – you are responsible for all material in the reading and in the homework problems. Problems: 1. Three identical masses of 500 kg each are placed on the x-axis. One mass is at x = -10cm, one is at the origin and one is at x = 40cm. What is the net gravitational force (magnitude and direction) on the mass at the origin, due to the other two masses? 2. Teams from two dormitories, East and West, are having a tug-of-war, pulling on opposite halves of a rope of negligible mass and weight. In this problem "Team East" means all their members + their half of the rope (total mass M E ), while "Team West" means all their members + their half of the rope (total mass M W ). (a) Draw two carefully labeled free-body diagrams showing the forces acting on "Team East" and those acting on "Team West." You may treat each team as a particle. Please identify each force by its interaction type and the body providing it. Use the notation introduced in class.
