Question

An object of mass 2 kg is held at the top of a triangular wedge as shown in the figure, and then released. The reference level for potential energy is at the base of the triangle. Neglect friction and use g= 10 m/s squared. What is gravitational potential energy of the object at the top of the wedge?
