Question

A 0.19-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 4.6 m. 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?

Answer 1

2.048 J

Step-by-step explanation:

mass of stone, m = 0.19 kg

h = 1.1 m

g = 9.8 m/s^2

Gravitational potential energy, U = m x g x h

U = 0.19 x 9.8 x 1.1

U = 2.048 J

Thus, the potential energy of the stone is 2.048 J.
