To determine
(a)
To find:
The work done if the gorilla reaches the height of 20ft in 10 seconds
Answer
7200 ft·lb
Explanation
1) Concept:
Use the formula for work done. Work done does not depend on the amount of time.
2) Formula:
W=F·d
Where F is force and d is distance
3) Given:
i. F=360 lb
ii. d=20 ft
4) Calculation:
The work done by the gorilla to climb the tree to reach a height of 20 ft in 10 seconds is by using the formula
W=F·d
Substitute the given values
W=360·20
Simplify,
W=7200 ft·lb
Conclusion:
Therefore,
The work done by the gorilla to climb the tree to a height of 20 ft10 seconds is 7200 ft·lb
To determine
(b)
To find:
The work done if the gorilla reaches the height of 20ft in 5 seconds
Answer
7200 ft·lb
Explanation
Since the work done does not depend on the amount of time taken by the gorilla to climb
Therefore, work done remains the same as calculated in part (a)
That is %<([a-z0-9]+)>𝑊=7200 𝑓𝑡·𝑙𝑏
Conclusion:
Work done by the gorilla to climb the tree to a height of 20 ft in 5 seconds is 7200 ft·lb
