    Answer: 5937.5 joules

    Explanation:

    kinetic energy of car K. E = ?

    Mass of car M = 475kg

    speed of car V = 5m/s

    The Kinetic energy of an object is the energy possessed by the moving object, and it depends on its mass and speed.

    Thus, K. E = 1/2 x mass x velocity^2

    K. E = 1/2 x 475kg x (5m/s) ^2

    K. E = 0.5 x 475 x 25

    K. E = 5937.5 joules

    Thus, the kinetic energy of a car is 5937.5 joules
