A0.24-kg stone is held 1.2 m above the top edge of a water well and then dropped into it. the well has a depth of 4.8 m. (a) relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stoneâearth system before the stone is released? 14.112 incorrect: your answer is incorrect. your response differs from the correct answer by more than 100%. j (b) relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stoneâearth system when it reaches the bottom of the well? 0 incorrect: your answer is incorrect. the correct answer is not zero. j (c) what is the change in gravitational potential energy of the system from release to reaching the bottom of the well?
