ACCELERATION Describe a ball's motion as it rolls up a slanted
driveway. It starts with an initial velocity of 1.25 m/s up the ramp. It
travels upward, while slowing down, for 4.22 s, stops for an instant,
and then rolls back down. What are the direction and the magnitude
of the ball's acceleration as it rolls up the driveway?
1. ANALYZE AND SKETCH THE PROBLEM
