To increase the acceleration of the ball, the bowler should throw the ball with more force. According to Newton's second law of motion, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass (F = ma).
Therefore, the correct response is: The bowler should choose a ball with less mass or throw the ball with more force.
Choosing a ball with less mass will make it easier to achieve greater acceleration, and applying more force will also result in greater acceleration, regardless of the mass.
