Short Answer
A typical incandescent light bulb consumes 75 W of power and has a mass of 30 g. You
want to save electrical energy by dropping the bulb from a height great enough so that the
kinetic energy of the bulb when it reaches the floor will be the same as the energy it took to
keep the bulb on for 1.0 hour. From what height should you drop the bulb, assuming no
air resistance and constant g?
