Under conditions of conservation of energy where the initial energy object is only gravitational potential energy and the final energy is only kinetic, write an equation to calculate the final velocity of the object. Ignore all friction. Show all work Name two of the four common boundary conditions we set when discussing gravitational potential energy?
