Ballistic pendulum a bullet of mass m and velocity Vo plows into a block of wood with mass M which is part of a pendulum. How high h does the block of wood go? Is the collision elastic or inelastic?

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
