A 1200kg car reaches a speed of 11 m/s from rest in 10 seconds. Determine the cars power.

Divide the final kinetic energy by 10 seconds. That will be the power in Watts.
746W = 1 horsepower, if you want to convert to those units.
11 m/s is pretty slow for a car. Some humans can run that fast. To take 10 seconds to reach that speed is much too long for highway driving.
