    Answer:

    v = 1.63 m/s

    Explanation:

    Given that,

    The mass of a car, m = 1500 kg

    The kinetic energy of a car, K = 2004 m/s

    We need to find the speed of a car. The formula for the speed of a car is given by :

    K=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2K}{m}} \\\\v=\sqrt{\dfrac{2\times 2004}{1500}} \\\\v=1.63\ m/s

    So, the speed of the car is equal to 1.63 m/s.
