A 1.0-kg ball with a speed of 4.5 m/s strikes a 2.0-kg stationary ball. If the collision
Question:
A 1.0-kg ball with a speed of 4.5 m/s strikes a 2.0-kg stationary ball. If the collision is completely inelastic, (a) what are the speeds of the balls after the collision? (b) What percentage of the initial kinetic energy do the balls have after the collision? (c) What is the total momentum after the collision?
THINKING IT THROUGH. Recall the definition of a completely inelastic collision. The balls stick together after collision; kinetic energy is not conserved, but total momentum is.
