STEFFANY YACOVETTI MENA KARN

We are dropping the dollar coin to find out its speed. We are also going to calculate the speed if we were to drop if off the empire state building.

Supplies: Digital Camera Dollar Coin Logger Pro Stairway Internet Yard Stick Candy Bar

Pictures: Data: 1453 feet 443.2 meters (distance of empire state building)

Calculations: 5.9m/s=? 2.3 443.2 2614.88/2.3= 1136.3913 m/s

Conclusion: The speed of the coin when we dropped it off the stairway was 5.9 m/s. Our conclusion for the empire state building's is that if we continue the speed of the coin it would be 1136.3913 m/s, but on the other hand we see that this impossible because the air resistance would keep it from going straight down. The coin would also probably flip around while going down, so the speed time would be different (it might slow down).
