392 J
The potential energy (PE) of an object is given by the formula:
\(PE = mgh\)
Where:
- \(PE\) is the potential energy in Joules (J)
- \(m\) is the mass of the object in kilograms (kg)
- \(g\) is the acceleration due to gravity (approximately 9.8 m/s²)
- \(h\) is the height of the object above the ground in meters (m)
In this problem, we are given:
- \(m = 5\) kg
- \(g = 9.8\) m/s²
- \(h = 8\) m
Substituting these values into the formula, we get:
\(PE = (5 \text{ kg}) \times (9.8 \text{ m/s}^2) \times (8 \text{ m})\)
\(PE = 392 \text{ J}\)
Therefore, the energy of the object is 392 Joules.
