    Answer:0.14 kg

    Explanation:

    gravitational potential energy=gpe=116.62J

    Acceleration due to gravity=g=9.8m/s^2

    Height=h=85m

    gpe=m x g x h

    116.62=m x 9.8 x 85

    116.62=m x 833

    Divide both sides by 833

    116.62/833 = (m x 833) / 833

    0.14=m

    m=0.14 kg mass=0.14 kg
