calculate the potential energy of a 5 kg object sitting on a 3 meter ledge

Answer 1

To calculate the potential energy of the object, we can use the formula:

Potential Energy = mass * gravity * height

Given:
mass (m) = 5 kg
gravity (g) = 9.81 m/s^2 (acceleration due to gravity on Earth)
height (h) = 3 meters

Potential Energy = 5 kg * 9.81 m/s^2 * 3 meters
Potential Energy = 147.15 Joules

Therefore, the potential energy of the 5 kg object sitting on a 3 meter ledge is 147.15 Joules.
