- 1. Multiple ChoiceWhile playing pool, the white cue ball strikes the 8 ball. Before the collision, the cue ball's velocity was 10 m/s and the 8 ball was at rest. If both ball's have a mass of 0.15 kg and the cue ball's velocity after the collision is 2 m/s, what is the 8 ball's velocity?2 m/s8 m/s-2 m/s1.5 m/s
- 2. Multiple ChoiceIn a physics experiment, two carts of mass 1.5 kg each are rolled towards each other. The orange cart has a velocity of 2 m/s and the blue cart has a velocity of -1m/s. The carts stick together when they collide. Calculate their final speed.0.5 m/s1.0 m/s0.33 m/s0.67 m/s
- 3. Multiple ChoiceTwo football players with mass 75 kg and 100 kg run directly toward each other with speeds of 6 m/s and 8 m/s respectively. If they grab each other as they collide, the combined speed of the two players just after the collision would be:2 m/s3.4 m/s4.6 m/s7.1 m/s
