Potential Energy and Height Calculations

This video tutorial explains how to solve a problem involving potential energy. It begins by introducing the problem, which involves finding the height of a 15 kg object with a potential energy of 2646 joules. The video lists the given data, including the mass and potential energy, and explains the formula for potential energy (PE = mgh). The tutorial then demonstrates how to calculate the height by substituting the known values into the formula and solving for the height. The solution is found to be 18 meters. The video concludes with a summary of the solution process.
