1. Initially, a ball has a speed of 5.0 m/s as it rolls up an incline. Some time later, at a distance of 5.5 m up the incline, the ball has a speed of 1.5 m/s DOWN the incline. (a) What is the acceleration? What is the average velocity? How much time did this take? (b) At some point the velocity of the ball had to have been zero. Where and when did this occur?
