Question

Type the correct answer in the box. Find the gravitational potential energy of the stone. A stone weighing 1.5 kilograms is resting on a rock at a height of 20 meters above the ground. The stone rolls down 10 meters and comes to rest on a patch of moss. The gravitational potential energy of the stone on the moss is joules. (Use PE = mxgx h, where g = 9.8 N/kg.) ​

Answer 1

The gravitational potential energy of the stone on the moss is 294 joules.

Step-by-step explanation:

The gravitational potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height above the reference point.

In this case, the stone has a mass of 1.5 kg and is initially at a height of 20 meters. So, the gravitational potential energy of the stone is:

PE = (1.5 kg) × (9.8 m/s²) × (20 m) = 294 joules

Therefore, the gravitational potential energy of the stone on the moss is 294 joules.
