A car with mass of 1000.0 kg accelerates from 0 m/s to 40.0 m/s in 12.0 s. Ignore air resistance. The engine has a 21% efficiency, which means that 21% of the thermal energy released by the burning gasoline is converted into mechanical energy.

(a) What is the average mechanical power output of the engine?

(b) What volume of gasoline is consumed? Assume that the burning of 1.0 L of gasoline releases 41 MJ of thermal energy.
