Question

The ballistic pendulum (as shown) is an apparatus used to measure the speed of a fast-moving projectile such as a bullet. A projectile of mass m1 is fired into a large block of wood of mass m2 suspended from some light wires. The projectile embeds in the block, and the entire system swings through a height h. How can we determine the speed of the projectile from a measurement of h?
