    Answer:

    Explanation:

    His Kinetic energy = 1/2 m v^2

    v = 5 m/s

    m = 75 kg

    Ke = 1/2 75 * 5^2

    Ke = 937.5 Joules

    This will be converted to PE when he reaches the maximum height he reaches. In other words KE = PE

    PE = m * g * h

    m = 75

    g = 9.81

    h = ?

    PE = 937.5

    937.5 = 75 * 9.81 * h

    937.5 = 735.75 * h

    937.5/735.75 = h

    h= 1.27 meters
