Question

4. a) A solid truncated cone with smaller radius a and larger radius b, height h, and Determine the moment of inertia of the truncated cone in terms of a,b.p and central axis. 8 pts h when rotated about its b) A bullet of with a mass-m,is fired into the cone with a speed v, in the z direction. The bullet a +b above the central axis of the cone and lodges in the cone at the enters the cone at a ight same height (in the x-y plane as shown). Assuming that the cone can rotate freely about its central axis, determine the energy lost in this collision. 7 pts
