A rock of mass M is thrown from the edge of a cliff of height h with an initial velocity v at an angle with the horizontal, as shown in the figure Point P is the highest point in the rock's trajectory, and point Q is level with the initial position of the rock. All frictional forces are considered to be negligible. Which of the
following could correctly describe the total energy of the rock-Earth system at points P and Q?
