A car is moving such that its kinetic energy is 2.20×105 J. The car accelerates and the engine does 2.10×105 J of work to accelerate the car. What is the final kinetic energy of the car? Ignore energy lost to friction.

(Your answer must be accurate to at least 1%. Give your answer to at least three significant figures.)
