Concept explainers
(a)
The height gained by the baseball
(a)
Answer to Problem 36P
24.7 m.
Explanation of Solution
Given:
Initial velocity of the baseball
Final velocity of the baseball at the highest point
Acceleration experienced by baseball = acceleration due to gravity
Height gained by the ball
Displacement of the ball
Formula Used:
Displacement of an object in uniform accelerated motion is given as
Calculation:
Consider the motion of the baseball in vertical direction.
Displacement of the baseball is given as
Substituting the values
Conclusion:
Therefore, height gained is 24.7 m.
(b)
The time spent by the baseball in air
(b)
Answer to Problem 36P
4.5 seconds.
Explanation of Solution
Given:
Initial velocity of the baseball
Acceleration experienced by baseball = acceleration due to gravity
Time of travel
Displacement of the ball as it comes back to its starting location
Formula Used:
Displacement of an object in uniform accelerated motion is given as
Calculation:
Consider the motion of the baseball in vertical direction.
Substituting the values, to find the time.
Conclusion:
Therefore, time spent by baseball in air is 4.5 seconds.
