A) 1.3 W 
B) zero 
C) 2.5 W 
D) 5.0 W 
E) 2.2 W

Quizplus · Accepted Answer

The average power exerted by the squirrel can be calculated by dividing the work done by the time interval. If the work done is given or can be calculated from the force and displacement, the average power can be determined. Based on the options, 2.5 W is the most reasonable choice for average power.
