1) find out the Nissan Leaf mass (the actual car), add 74 kg for a typical test driver's mass and clculate its kinetic energy at 60 mph.
2) apply the work energy theorem to find the total work done to get a speed of 60 mph.
3) Calcualte the average power during the acceleration period of 9.9s.
4) Compare the power you calculated in (4) with the Leaf's advertised engine power of 80 kilowatts and give at least one reason for any difference between the two values

Your help would be appricated .. Thanks :)

You will need to look up the leaf mass for that car, but what is the formula for kinetic energy?
