    Answer: 1339.5 joules

    Explanation:

    Gravitational potential energy, GPE is the energy possessed by the jumper as he moves against gravity.

    Thus, GPE = Mass m x Acceleration due to gravity g x Height h

    Since Mass = 67kg

    g = 9.8m/s^2

    h = 2.04 metres

    Thus, GPE = 67kg x 9.8m/s^2 x 2.04m

    GPE = 1339.5 joules

    Thus, the gravitational potential energy at the highest point is 1339.5 joules
