A bullet with mass m and speed v is fired at a ballistic pendulum bob of mass M. The bob is attached to a thin, light rod of length L, hangs vertically initially, and is attached to a pivot at its top end. A) Find v so that the rod swings up and is horizontal at the maximum height of the bob. B) Find the minimum v so that the rod will make a complete circle. C) Find v so that the tension in the rod is zero at the top of its swing.
