Ballistic PendulumUsing Conservation of Momentum and Conservation of Energy to Determine the Speed of a Bullet

The kinetic energy of the bullet is not equal to the energy of the can and bullet, energy is dissipated in the inelastic collision

Δh = 0.32m – 0.29m = 0.03m

mb = 0.0005 kgmc = .195 kgVb = ?

Δh

Work backwards, find velocity of Bullet + Can (vb+c) just after the collision using energy:

Energy is NOT conserved in the inelastic collision but Momentum is:
