Potential Energy Height Calculation
The potential energy (PE) of an object is calculated using the formula:
\(PE = mgh\)
Where:
- PE is the potential energy
- m is the mass
- g is the acceleration due to gravity
- h is the height
We are given:
- PE = 600 J
- m = 20 kg
- g = 10 m/s2
Solving for Height (h)
To find the height h, we rearrange the formula:
\(h = \frac{PE}{mg}\)
Now, substitute the given values:
\(h = \frac{600 \text{ J}}{(20 \text{ kg})(10 \text{ m/s}^2)}\)
Perform the calculation:
\(h = \frac{600}{200} \text{ m}\)
\(h = 3 \text{ m}\)
The height of the object is 3 meters.
