The formula to calculate the potential energy of an object is: Potential Energy = m(mass)*g(gravity)*h(height) If we want to find the height of the object, we need to divide the potential energy by the mass and the gravity. The mass and potential energy is given and g=9.81 (rounded) here on earth so: [latex] frac{potential energy}{m*g} [/latex] = h [latex] frac{350}{17*9.81} [/latex] =2.098... ≈ 2.1 metres The shelf has a height of approximately 2.1 metres.
