__**Daily Question**__ Energy and Roller Coasters Worksheet

__**In Class Work**__ Mr. Manning was away. Instead we had a substitute named Mr. Marcello. He told us that we had to do the energy and roller coasters worksheet. There were three different problems we had to do. The first was: Frank, a San Francisco hot dog vender, Has fallen asleep on the job. when an earthquake strikes, his 400 kg cart rolls down Nob Hill and reaches point A at a speed of 8.00 m/s. How fast is the cart going at Point B. complete the chart. Point A was 50 m high and point B was 30m.

There were two other problems similar to the first one except they also had energy lost by friction. there was no homework.
