(a)
The total impulse acting on the ball.
(a)
Answer to Problem 20P
The total impulse on the ball is
Explanation of Solution
Given:
Mass of the tennis ball is 0.060 kg. Force acting on the ball is in +x direction.
The given graph is shown below.
Formula used:
The impulse is calculated as the area under the graph of force versus time.
Calculation:
Here, the area under the graph of Force versus time can be calculated as total area under the graph. The total number of boxes under the curve is
Conclusion:
The total impulse on the ball is
(b)
The velocity of the ball after being struck.
(b)
Answer to Problem 20P
The velocity of the ball after struck by force is
Explanation of Solution
Given:
Mass of the tennis ball is 0.060 kg. Force acting on the ball is in +x direction.
The given graph is shown below.
Calculation:
Using the values of impulse from the previous section, we can calculate the final velocity of the ball.
Conclusion:
The velocity of the ball after struck by force is
