- How do your predictions compare to the observed data? Explain at least two reasons for the differences.
- If you were to fire a paintball pellet horizontally and at the same time drop the same type of paintball pellet you fired from the paintball gun, which pellet would hit the ground first and why is this so?
- Suppose you altered your existing ramp so that the marbles had twice their initial velocity right before leaving the ramp. How would this change the total distance traveled and the time that the marbles were in the air?
- Describe the acceleration of the marbles after it leaves the ramp. Use kinematic equations to support your discussion.
