    = 3132.9 Joules

    Explanation:

    Kinetic energy is the energy possessed by a body when in motion. Kinetic energy is calculated by the formula; K. E = 1/2 mV², where m is the mass of the body or object, and V is the velocity. Therefore kinetic energy depends on the mass and the velocity of the body or the object in motion.

    In this case;

    Kinetic energy = 0.5 * 0.018 kg * 590²

    = 3132.9 Joules
