![Check Mark](/static/check-mark.png)
Answer to Problem 93A
The magnitude of the acceleration of the ball in the pitcher’s hand is 28.22 times the free-fall acceleration on Earth, that is
Explanation of Solution
Given:
A fastball is thrown at an initial speed of
Formula used:
Final velocity with constant acceleration is given by,
Where,
Calculation:
Since, no acceleration acts on the fastball till it reaches the pitcher’s hand, thus the initial velocity of the ball at the pitcher’s hand will be:
Finally, the ball is stopped, thus its final velocity will be 0, that is,
Now, using the above mentioned formula for the final velocity, the acceleration of the ball in the pitcher’s ball will be
Negative sign denotes the deceleration of the ball.
It is known that the free fall acceleration on Earth is
Then,
Conclusion:
Thus, the acceleration of the ball in the pitcher’s hand is
