    Answer:

    43,200 Joules

    Explanation:

    Kinetic energy can be found using the following formula:

    KE=\frac{1}{2}mv^2

    where m is the mass in kilograms and v is the velocity in m/s.

    We know the mass is 600 kilograms, and the car is moving at 12 meters per second. Therefore the mass is 600 kilograms and the velocity is 12 m/s.

    m=600

    v=12

    Substitute these values into the formula.

    KE=\frac{1}{2}600*12^2

    First, evaluate the exponent: 12^2. 12^2 is the same as 12*12, which is equal to 144.

    KE=\frac{1}{2}*600*144

    Multiply 600 and 144

    KE=\frac{1}{2}*86,400

    Multiply 1/2 and 86,400, or divide 86,400 by 2.

    KE=43,200

    Add appropriate units. Kinetic energy uses Joules, or J for units.

    KE=43,200 Joules

    The kinetic energy of the car is 43,200 Joules.
