1. A sports car moving at a constant velocity travels 120 m in 5.0 s. If it then brakes and comes to a stop in 4.0 s, what is the magnitude of its acceleration (assumed constant) in m/s^2 and in g's (g=9.80 m/s^2).
2. A car slows down from 28 m/s to rest in a distance of 88 m. What was its acceleration, assumed constant?
