    Answer:

    112 J

    Explanation:

    The kinetic energy of a body is given as:

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

    where m = mass

    v = velocity

    The mass of the ball is 3.5 kg.

    The velocity of the ball is 8 m/s.

    The kinetic energy of the ball is therefore:

    KE = \frac{1}{2} * 3.5 * 8^2\\ \\KE = 112 J
