Balance one penny on the edge of a table. Place your index finger on a second penny, then flick the second penny so that it travels off the table, while the first penny is gently nudged off the edge. It may take a few practice trials to be able to do this effectively.

1. Predict which penny will land first, the penny moving horizontally or the one that simply drops off the table. Explain.
2. what will happen if you increase the speed of the second penny?
3. What if you increase the height from which the pennies are dropped?
4. Does horizontal spoed of the flicked penny affect the impact times of the pennies?
5. What can you say about the time to hit the floor for each penny?
