The rock's PE is 29400 joules.
The potential energy of the rock can be calculated using the formula: potential energy = mass × gravity × height. Given the mass of the rock (10.2 kg), the height of the hill (300 meters), and the acceleration due to gravity (approximately 9.81 m/s^2), the potential energy would be 10.2 kg × 9.81 m/s^2 × 300 m = 29970.6 Joules.
its physics term for the fact that it is not in motion (kinetic energy) but it is above the ground, so at any moment it could "potentially" have kinetic energy by falling to the floor.
The potential energy of the object is given by the formula: potential energy = mass * gravitational acceleration * height. Plugging in the values: potential energy = 5 kg * 9.8 m/s^2 * 3 m = 147 Joules.
The word in your question that I keyed on is "resting". An object at rest has zero kinetic energy. If you meant potential energy, the answer is 1500 joules.
Potential energy, specifically gravitational potential energy, since the book has the potential to fall due to gravity when it is on the high shelf.

When potential energy is high, kinetic energy is low.
Beginning with its potential energy, which is converted to kinetic energy when it falls
Use one of the formulas for constant acceleration to calculate how many meters the brick will fall after 2 seconds. Subtract this from the 30 meters, to see how high the brick is above ground. Finally, use the formula for potential energy: PE = mgh, to calculate the potential energy.
The idea is to use the formula for potential energy: PE = mgh. Replace the numbers you know, and solve for the missing number.
