The resistance of an exercise bike is often provided by a generator; that is, the energy that you expend is used to generateelectric energy, which is then dissipated. Rather than dissipatethe energy, it could be used for practical purposes.a. A typical person can maintain a steady energy expenditureof 400 W on a bicycle. Assuming a typical efficiency forthe body, and a generator that is 80% efficient, what usefulelectric power could you produce with a bicycle-poweredgenerator?b. How many people would need to ride bicycle generatorssimultaneously to power a 400 W TV in the gym?
