(a)
To draw: The arrows showing the momentum of the ball before and after bat hits the ball.
(a)
Answer to Problem 13SSC
The sketch of the arrows showing the momentum of the ball before and after bat hits the ball is shown in Figure 1.
Explanation of Solution
Given:
The mass of the ball is
The velocity of the ball before hitting the bat is
The velocity of the ball after hitting the bat is
Calculation:
Consider a ball is moving in the positive
Sketch the vector diagram for the momentum of the ball before and after hitting the ball.
Figure 1
Conclusion:
Thus, the sketch of the arrows showing the momentum of the ball before and after bat hits the ball is shown in Figure 1.
(b)
The change in the momentum of the ball.
(b)
Answer to Problem 13SSC
The change in the momentum of the ball is
Explanation of Solution
Given:
The mass of the ball is
The velocity of the ball before hitting the bat is
The velocity of the ball after hitting the bat is
Formula used:
Change in momentum is,
Calculation:
Consider a ball is moving in the positive
The change in the momentum of the ball is,
Conclusion:
Thus, the magnitude of change in the momentum of the ball is
(c)
The impulse delivered by the bat.
(c)
Answer to Problem 13SSC
The impulse delivered by the bat is
Explanation of Solution
Given:
The mass of the ball is
The velocity of the ball before hitting the bat is
The velocity of the ball after hitting the bat is
Formula used:
Impulse is,
Calculation:
Consider a ball, moving in the positive
The impulse delivered by the bat is,
Conclusion:
Thus, the impulse delivered by the bat is
(d)
The average force exerted by the bat on the ball.
(d)
Answer to Problem 13SSC
The force exerted by the bat on the ball is
Explanation of Solution
Given:
The mass of the ball is
The velocity of the ball before hitting the bat is
The velocity of the ball after hitting the bat is
The time of contact of the bat and the ball is
Formula used:
Force in terms of impulse is,
Calculation:
Consider a ball, moving in the positive
From part (b), the impulse delivered by the bat to the ball is
The force exerted by the bat to the ball is,
Conclusion:
Thus, the force exerted by the bat on the ball is
