21:28 616BMB 100N + Problem 2: Conical Top Consider a rigid top consisting of the solid cone in problem 1. Suppose the top is spun around an axis through the tip of the cone and the center of mass to an angular speed W. The top spins without precessing, meaning that the direction of the angular momentum aligus with HW #6 PHYS 22 May 10, 2022 the vertical z axis. In order to spin up the top, a rope is wound around the edge of the circular face of the top and the rope is pulled with a constant force. 1. What is the magnitude of the torque needed to spin-up the top from rest, if the torque is applied through one full revolution? 2. After the top begins spinning, you perturb it slightly by tilting the axis of rotation so that it makes an angle 8 with the vertical axis. Draw a free body clingram and label all the appropriate forces and the torque on the top. Use this to find the angular speed A at which the top precesses around the vertical axis.
