Amotorcycle uses 50 000 kilojoules per minute. if 15 percent of the 15 energy generated by its engine is lost in the first few seconds, how much energy, in kilojoules, remains to power the motorcycle?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force
