Consider the ballistic pendulum setup: A bullet of mass m with speed vo hits a pendulum bob of mass M, suspended by a massless rope of length L. The bullet gets stuck inside, making the pendulum swing up to some height. The maximum height the pendulum can reach is solved below: L m M Solution: At the start, the bullet has a momentum muo. When they collide and the bullet gets inside, the speed of the combined masses can be obtained using conservation of linear momentum. muo (m+ M)v, where u is the speed of the combined masses.
