Answer:

7360 ft·lb

Explanation:

You want the work done by a 320-lb gorilla climbing to a height of 23 feet.

Work

Work is the product of force and distance:

W = (weight)·(height) = (320 lb)(23 ft) = 7360 ft·lb

The gorilla does 7360 ft·lb of work.

__

Additional comment

Time comes into play when you want the power involved. If the climbing is done in 10 seconds, the power required is about 1.34 horsepower. (1 hp = 550 ft·lb/s)
