1. Were the collisions elastic or inelastic? EXPLAIN. Inelastic, Because the kinetic energy will be changed to some other form of energy in the collision. 2. Was momentum conserved during the collisions? EXPLAIN. 3. Was mechanical energy (E= K+U) conserved during the collisions? EXPLAIN. 4. Was the momentum of the pendulum and the ball conserved after collision? EXPLAIN.
