Problem
Two identical stones A and B, each of mass 0.5kg, are held at heights 8m and 5m respectively above the same horizontal ground. Take g=9.8m/s2.
(i) Find the difference in their gravitational potential energies.
(ii) To make stone B have the same gravitational potential energy as stone A, how much additional height must it be raised?
