Pre-laboratory Work:
Part P-1:
Let's consider the ballistic pendulum apparatus as pictured on previous page. A spring gun
projects the ball horizontally, into a hollow bob that catches the ball. Below is a drawing of
the three stages of this action.
At Collision
(inelastic)
Before Collison
After Collision
1. In an inelastic collision, what is conserved and what is not conserved? Explain.
2. Use mj for the mass of the ball, m2 for the mass of the pendulum, vị for the velocity of the
ball and v2 for the velocity of the ball and pendulum together.
