Human-powered aircraft require a pilot to pedal, as in a bicycle, and produce a sustained power output of about 0.30 hp. The Gossamer Albatross flew across the English Channel on June 12, 1979, in 2 h 49 min.
(a) How much energy did the pilot expend during the flight?
(b) What is the minimum number of Snickers bars (280 Cal per bar) the pilot would have to consume to be "fueled up" for the flight?
