We can find the power output by the engine by taking the work done on the car divided by the time it took to do that work. To find the work done on the car, we just need to figure out how much energy was given to the car. In this case, the car was given kinetic energy and it took two seconds to give it that kinetic energy.
In physics, power is the rate of doing work or of transferring heat, the amount of energy transferred or converted per unit time. Having no direction, it is a scalar quantity. In the International System of Units, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenthcentury developer of the condenser steam engine.

Power is defined as the rate at which work is done, Power = Work / time. Work is the change in energy. Work done on an object can give that object either potential energy or kinetic energy. There are several different forms of potential energy, the most common being gravitational potential energy, which is the energy due to an objects mass and ...
The concepts of work and energy are closely tied to the concept of force because an applied force can do work on an object and cause a change in energy. Energy is defined as the ability to do work. Acting force changing with position. In this example, the total work accomplished is (1/2)(15)(3 ...
