1. A 3-kg sphere makes and inelastic collinsion with a second sphere initially at rest. The two spheres move with a speed equal to one third of the original speed of the 3-kg sphere. What is the mass of the second sphere?
2. A bumper car at an amusement park ride traveling at 0.8m/s collides with an identical car at rest. This second car moves away with a speed of 0.5 m/s. What is the velocity of the first car after the collision?
