Calculating Changes in Gravitational potential Energy Calculate the work required to lift a 1.00 kg object from sea level to the top of Mount Everest, which has an elevation of 8848 m. Assume that Earth is spherical with a radius of 6371 km. Perform the calculation in the following two ways: Use the mgh expression for potential energy, and assume that g remains constant at its value at sea level, 〖9.81m/s〗^2. Use Equation (11-8).
