Our balloon car weighed 125 grams (grahams). If it were 125 Grahams, Elizabeth would be really, REALLY happy. It went 151 centimeters, which really isn't that far. Our group was infatuated with the idea of using a slingshot, or "chicken". It went this distance in 5 seconds. I find this disappointing.
The acceleration is 6.04 centimeters per seconds squared. 6.04 times 125 equals 755. Force = mass x acceleration, so the force is 755 newtons. The velocity is 30.2 delta v over delta t. I shall post pictures later....if I feel like it.
Hey! Here is a link to my blog for anyone (yes you Mr. Harrelson) who would like to see a beautiful picture of the balloon car. Thanks to Mr. Harrelson for taking the picture: http://treefrogscience.blogspot.com/2011/02/balloon-car.html .
