A 85 kg rock climber first climbs 50 m up to the top of a quarry, then descends 75 m from the top to the bottom of the quarry. If the initial height is the reference level, find the potential energy of the system (the climber plus Earth) when the climber is at the top. Find the potential energy of the system when the climber is at the bottom.
