A new bowling alley has just opened in which the lanes are not horizontal, but slope upward slightly from where you release the ball to where the pins are standing. The lanes in this new bowling alley are highly polished, so there is no friction between the ball and the floor. Moreover, the ball never moves fast enough for air resistance to effect its motion. Once you release the ball and allow it to roll on its own up one of these lanes, the ball
A. moves uphill because of the uphill acceleration on the ball.
B. moves with a constant velocity because of Newton's first law; an object in motion tends to remain in motion.
C. slows down because of the downhill acceleration on the ball.
D. decelerates because of the uphill velocity of the ball.
