Question

0.18-kg stone is held 1.1 m above the top edge of a water well and then dropped into it. The well has a depth of 4.5 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? \& J

Answer 1

The gravitational potential energy of the stone-Earth system before the stone is released is 1.96 Joules.

Step-by-step explanation:

The gravitational potential energy of the stone-Earth system before the stone is released can be found using the equation:

Gravitational Potential Energy = mass x gravitational acceleration x height

Given that the mass of the stone is 0.18 kg, the height is 1.1 m, and the gravitational acceleration is 9.8 m/s^2, we can plug in these values to calculate the gravitational potential energy:

Gravitational Potential Energy = 0.18 kg x 9.8 m/s^2 x 1.1 m = 1.96 J

Therefore, the gravitational potential energy of the stone-Earth system before the stone is released is 1.96 Joules.
