A gasoline engine takes in1.61×104 {\rm J} of heat and delivers3900 {\rm J} of work per cycle. The heat isobtained by burning gasoline with a heat of combustion of4.60×104 {\rm J}/{\rm g}.
a) How much heat is discarded in eachcycle?
b) If the engine goesthrough 62.0 cycles per second, what is its power output in kilowatts?
c) If the engine goesthrough 62.0 cycles per second, what is its power output in horsepower?
