Question

To increases the final momentum of a racquetball, the player should:

a. swing the racquet as fast as possible
b. follow through when hitting the ball
c. increase contact time with the ball
d. all of the above

Answer 1

To increase the momentum of a racquetball, a player should swing the racquet fast, follow through upon hitting, and increase contact time with the ball. Hitting the ball at the 'sweet spot' of the racquet also maximizes velocity and reduces vibration.

Step-by-step explanation:

To increase the final momentum of a racquetball, a player should consider multiple factors:

1. Swing the racquet as fast as possible to increase the speed of the ball upon impact.
2. Follow through when hitting the ball to ensure that the maximum force is transferred over a longer period, enhancing the acceleration of the ball.
3. Increase contact time with the ball, which can allow for a greater transfer of momentum from the racquet to the ball.

The correct answer is therefore d. all of the above. Additionally, hitting the ball at the racquet's sweet spot minimizes vibration and maximizes velocity, without exerting excess force on the player's hand. Understanding the physics principles such as momentum, rotational motion, and vibrations can aid in improving a player's technique and reducing the risk of sports injuries.
