Ballistic Pendulum Using 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 mb = 0.0005 kg mc = .195 kg Vb = ? Work backwards, find velocity of Bullet + Can (vb+c) just after the collision using energy: Δh = 0.32m – 0.29m = 0.03m Energy is NOT conserved in the inelastic collision but Momentum is:
