Momentum, Impulse & Collisions: Ballistic Pendulum, An Explanation

A ballistic pendulum is a device for measuring a bullet's momentum, from which it is possible to calculate the bullet's velocity and kinetic energy. In this video I will go through the three steps that can be used to determine the velocity of a bullet just before it collides with the ballistic pendulum.
