To increase the acceleration of the bowling ball, the bowler should throw the ball with more force. According to Newton's second law of motion (F = ma), acceleration (a) is directly proportional to the force (F) applied and inversely proportional to the mass (m) of the object.
Therefore, if the bowler wants to increase the ball's acceleration, they should choose a ball with less mass, or they should throw the ball with more force. The other options of using a heavier ball or throwing it with less force would not result in greater acceleration.
So the preferred response is: The bowler should choose a ball with less mass or throw the ball with more force.
