To increase the ball's acceleration, the bowler should apply more force to the ball. According to Newton's second law of motion (F = ma), acceleration (a) is directly proportional to the force (F) applied to the mass (m) of the ball. Therefore, the correct response would be:
The bowler should choose a ball with less mass or throw the ball with more force.
This allows for greater acceleration of the ball, helping it to effectively reach all the pins.
