    Answer: its is you figer it out okay haha

    Step-by-step explanation: im jokeing

    Kinetic energy = 1/2 M V2

    At the lower speed, the car's KE is (500) (1) 2 = 500 joules

    At the higher speed, the car's KE is (500) (2) 2 = 2,000 joules

    The difference is the energy i. e. the work you have to put into it

    to raise the speed from 1 m/s to 2 m/s.

    (2,000 - 500) = 1,500 joules there u go : D
