Problem

Block A of mass

3\,\text{kg}

is placed

2\,\text{m}

above the ground, while block B of mass

4\,\text{kg}

rests

1.5\,\text{m}

above the ground. Taking

g = 9.8\,\text{m s}^{-2}

, determine which block has the greater potential energy and calculate the difference in their potential energies.
