2.4 m/s^2 6.0 m/s^2 11.5 m/s^2 24.0 m/s^2
I gave my students this multiple choice question: Laura prepared to roll a bowling ball down a lane. She swung the ball back with her arm. At the top of her backswing, the ball had a velocity of 0 meters per second (m/s). She swung her arm forward to release the ball down the lane. The ball left her hand with a velocity of 12 m/s. The time it took her to swing the ball forward was 0.5 seconds. What was the average acceleration of the bowling ball during her forward swing?

Only one answer is correct among these 4 choices:
- 2.4 m/s^2
- 6.0 m/s^2
- 11.5 m/s^2
- 24.0 m/s^2

Could you tell me which one is correct?

24.0 m/s^2
