Problem

Block A of mass 3 kg3\,\text{kg} is placed 2 m2\,\text{m} above the ground, while block B of mass 4 kg4\,\text{kg} rests 1.5 m1.5\,\text{m} above the ground. Taking g=9.8 m s−2g = 9.8\,\text{m s}^{-2}, determine which block has the greater potential energy and calculate the difference in their potential energies.
