Task:To experience G-force of free-fall and calculate distance and maxiam velocity of the car.

Concepts:Observation, thinking, concepts, data

Directions:
1.Measure thime of free-fall didtance
2.Use this measured time to calculate free-fall distance.
3.Calculate maxium velicity of the car.
4.Use vertical accelerometers ro measure G's durning free-fall and durning braking.
5.Use the horizontal accelerator and trigometric functions, calculate the height of the Hellevator. Compare with the given height and find the percentage of error.
6.Calculate your potential energy at the top of the Hellevator.
