1. The problem statement, all variables and given/known data A spoon is raised 21.0 cm above a table. If the spoon and it's contents have a mass of30.0g, what is the gravitational potential energy associated with the spoon at that height relative to the surface of the table? 2. Relevant equations I know that the equation for gravitational potential energy is PEg=mgh 3. The attempt at a solution I know that the mass is 30.0g and the height is 21.0 cm. But how would you figure out the free-fall acceleration?
