    Kinetic energy = 1/2 * m * v^2

    mass m = 950kg

    Velocity v = 13m/s

    Kinetic energy = 1/2 * 950 * 13^2

    Kinetic energy = 475 * 169

    Kinetic energy = 80275J

    Answer: 80,275 J

    Explanation: Kinetic energy is expressed as KE = 1/2 mv²

    so substitute the given values of mass and velocity. KE = 1/2 (950kg) (13m/s) ² = 80,275 J.
