Question

1B. A baseball with a mass of LaTeX: 0.145 kg 0.145 k g is thrown to the left at a speed of LaTeX: 42.0 m/s 42.0 m / s. The ball is struck by a bat and leaves the bat with a speed of LaTeX: 49.0 m/s 49.0 m / s. If the time of the collision is LaTeX: 0.700 ms 0.700 m s, what is the average force of the bat on the ball? Neglect air resistance and assume the mass of the bat is so much larger than the ball that the bat does not rebound at all in the collision. Be careful with your signs. You must observe direction in this equation. What is the impulse of the bat on the ball? What is the momentum of the ball after it is hit by the bat?

    PRACTICE IT Use the worked example above to help you solve this problem. A golf ball with mass 5.70 x 10 2 kg is struck with a club as shown in the figure above. The force on the ball varies from zero when contact is made up to some maximum value (when the ball is maximally deformed) and then back to zero when the ball leaves the club, as in the graph of force vs. time in the figure below....
