To increase the acceleration of the ball, the bowler should consider the relationship defined by Newton's second law of motion, which states that acceleration (a) is equal to the net force (F) acting on an object divided by its mass (m): \( a = \frac{F}{m} \).
For the bowler to achieve greater acceleration, they should throw the ball with more force or choose a ball with less mass. Thus, the best option from your provided choices is:
The bowler should choose a ball with less mass or throw the ball with more force.
