A chipmunk (mass of approximately 1 kg) does push-ups by using a force of 5 N to elevate its center-of-mass by 6 cm in order to do 0.70 Joule of work. If the chipmunk does all this work in 2 seconds, what is its power?
Answers: 2
on average.
is equal to the product of force 
and the speed 
at which that force moves the object. That is: 
.On the other hand, average power 
is done. In other words, average power 
is the average work done in unit time. If work 
is done in time 
, the average power would be 
. Â
