Question

1. a) We are all on a bus, driven by Dr. Gallaher, traveling to the conference of the American Physics Sociery at the convention center. The bus is stopped at a red light in front of AJP, and Dr. G's favorite death metal band is about to start playing to open the convention festivities. He floors the bus, only to find out the gas pedal gets stuck in the gum he just spit out. Find our average acceleration in m/s^2 if we cruise through the next intersection exactly 1235 meters away in 6.57 seconds.

b) If, overall, Dr. G has driven at 125 mph for 2.10 minutes and 15.0 mph for 16.0 minutes to get downtown, how far have we traveled (miles)? What is the overall average speed in mph?
