A 0.28-kg stone is held 1.4 m above the top edge of a water well and then dropped into it. The well has a depth of 5.1 m. (a) Taking y = 0 at the top edge of the well, what is the gravitational potential energy of the stone-Earth system before the stone is released? x Your response differs from the correct answer by more than 10%. Double check your calculations. J (b) Taking y = 0 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? Your response differs from the correct answer by more than 10%. Double check your calculations. J (c) What is the change in gravitational potential energy of the system from release to reaching the bottom of the well? X Your response differs from the correct answer by more than 10%. Double check your calculations. J A 0.28-kg stone is held 1.4 m above the top edge of a water well and then dropped into it. The well has a depth of 5.1 m.
