In a carnival game you roll a ball up a ramp and into a basket. during one attempt, you roll the ball so that it has a velocity of 6.0 m/s i^ at the bottom of the ramp and 2.0 m/s i^ at the top (where i^ points up the ramp). if it takes 1.5 s for the ball to roll from the bottom to the top of the ramp, the ball’s average acceleration is m/s2 i^.
