A ballistic pendulum consists of a thin rod AB (length = 2.00 m; mass = 0.75 kg) that is rigidly attached to a solid sphere that has a center C, radius = 0.40 m, and mass = 5.00 kg. A bullet (mass = 0.02 kg) is fired at point C with an unknown speed vv. You may assume that the bullet embeds itself inside the sphere precisely at point C and that the mass lost by the sphere during the impact due to the bullet is negligible. Immediately after the impact, measurements indicate that the system has 21.23 joules of kinetic energy. Determine the speed of the bullet.
