blog spot from sept. 8.(I thought i has posted it but i guess it never worked. sorry)

Today in class we reviewed the engineering a "photo finish" lab. Some of the major points that we hit were the slope is defined as rise/run which equals a change in v over a change in t which also equals acceleration. Another point is that the final velocity of the cart should be 2x as large as the velocity of the buggy. The second half of class we worked on the photo finish follow up. On this worksheet it has three different graphs and we compared the buggy to the cart on the ramp on position vs. time and velocity vs. time graphs.
