    Explanation: The last question before this states the hiker's mass, which is 50kg.

    The Gravity on earth is 9.8 m/s

    Height is 60m high

    Put that into this: PE = mgh

    M = mass

    G = Acceleration due to Gravity

    H = Height in Meters

    Now Solve.

    Here we do not have the mass of the hiker, but we can answer it for a more general case, suppose that the mass of the hiker is M

    For lifted objects, the only force acting on them is the force of gravity, and this force is equal to the mass times the gravitational acceleration, or:

    Fg = M*g where g is equal to 9.8m/s^2

    Now, the potential energy also depends on the distance that the object will move is it starts to fall, this distance h is the distance of the cliff for example, so we have:

    PE = M*g*h

    where the value of g is already known and the value of h is 60m
