Name (Last, First) ____________ , ____________ Recitation TA ____________ Section Number_______ Physics 151 Problem Set #6 due ______________________ Answer Structure [4 pts] _________ 1. [8 points] Two students want to raise a heavy box onto the back of a truck. They do this by putting a rope through a handle on the box, and each lifting one side of the rope, as sketched. The arrangement is symmetrical, so that the rope makes an angle φ with the horizontal on either side. The box is moved at a constant speed. In this problem you will compute the magnitude of the tension in the rope. Let the mass of the trunk (including the handle) be M , and neglect the mass of the rope. a) Draw a free body diagram of the forces on the handle beside the “real world” picture below. φ φ M b) Choose a sensible coordinate system, and write each of the forces in terms of your coordinates. You may use either vector notation, or ordered pairs. c)
