A0.23-kg stone is held 1.5 m above the top edge of a water well and then dropped into it. the well has a depth of 4.6 m. (a) relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stone−earth system before the stone is released? j (b) relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stone−earth system when it reaches the bottom of the well? j (c) what is the change in gravitational potential energy of the system from release to reaching the bottom of the well?
