d) 1.7 m
The formula for potential energy is PE = mgh, where m is the mass, g is the acceleration due to gravity (9.81 m/s^2), h is the height, and PE is the potential energy. Rearranging the formula, we get h = PE/mg.
Plugging in the given values, h = 1000.0 J / (60.0 kg x 9.81 m/s^2) = 1.7 m. Therefore, the height of the hill is 1.7 meters.
