Required information

A car with mass of 1035 kg accelerates from 0 m/s to 40.0 m/s in 10.0 s. Ignore air resistance. The engine has a 22.0% efficiency, which means that 22.0% of the energy released by the burning gasoline is converted into mechanical energy.

What is the average mechanical power output of the engine?

_______kW

Hint: How can you relate power, energy and time? Is there any potential energy involved in this problem?

What volume of gasoline is consumed? Assume that the burning of 1.00 L of gasoline releases 46.0 MJ of energy.

_______L Hint: Given the energy content of the gasoline, how can the chemical energy actually provided by the engine be found?
