Physics

To calculate the average power output of the engine, we need to find the work done by the engine and divide it by the time taken.

 

Calculate the work done by the engine

The work done by the engine is equal to the change in kinetic energy of the car.

 

The kinetic energy () is given by:

Where:

is the mass of the car (1500 kg),

is the velocity of the car.

 

We calculate the initial and final kinetic energy:

- Initial kinetic energy () when the car is moving at 10 m/s:

- Final kinetic energy () when the car is moving at 25 m/s:
