Your goal in this experiment is to determine the acceleration of a cart as it rolls down a tilted track. You have the following equipment:

- a track with attached tape measure
- one wooden block
- a cart
- a stopwatch

Measure the time it takes for the cart to roll
from a standing start the following distances:
**20 cm, 30 cm, 40 cm, 50 cm **.
Make three trials at each distance.

Write down your results in a table which looks something like this:

2 2 Distance (cm) Time to roll (s) avg time (s) (avg time) (s) 1 2 3 +/- +/- ---------------------------------------------------------------------------- 20 30 40 50 ----------------------------------------------------------------------------

Use your measurements to make a graph which corresponds to the following equation:

What is the acceleration of the cart? Be sure to include both a value and an uncertainty.

If you have time:Is there any way to compute this acceleration, theoretically? If so, how does the theoretical acceleration compare to your measured value?
