A bowler throws a ball down the lane toward the pins. The ball reaches the pins and slowly moves through them, knocking down the center pins but leaving the end pins standing. The bowler wants the ball to reach all the pins. Which changes should the bowler make so that the ball has a greater acceleration?(1 point)

To increase the acceleration of the ball and improve the chances of knocking down all the pins, the bowler should choose a ball with less mass or throw the ball with more force.
Explanation:
To understand why these changes will increase the acceleration, let's look at Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a). In this case, we want to increase the acceleration of the ball.
If the bowler chooses a ball with less mass, the force required to achieve the same acceleration will be smaller. According to Newton's second law, if the mass of the ball is smaller, the force required to accelerate it will also be smaller. Therefore, choosing a ball with less mass will increase the ball's acceleration.
Alternatively, the bowler can also increase the force with which they throw the ball. By exerting a greater force on the ball during the throw, more force is applied to accelerate the ball. This increase in force will result in greater acceleration.
In conclusion, to increase the ball's acceleration and improve the chances of knocking down all the pins, the bowler should choose a ball with less mass or throw the ball with more force.
