This is my question.

Suppose the power output you found in Question 6 is the same power you could produce on a stationary bike, and suppose we hooked up a mechanical generator to the bike, and we hooked up lightbulbs to the output of the generator. How many 60 W lightbulbs could you power (simultaneously) by riding the bike as hard as you can? Would you be able to keep them running for very long? Explain your reasoning.

I have the power output of 469.402 watts in question 6.

What kind of calculations do I need to do to find these answers?

Thanks!
