Given:
Height, h = 3.00 meters
Mass, m = 0.5 N
Let's find the potential energy.
To find the potential energy, apply the formula:

Where:
• m is the mass in kilograms
,
• g is acceleration due to gravity = 9.8 m/s²
,
• h is the height in meters
Let's convert the mass from Newtons to kilograms.

The mass in kilograms is 0.05 kg.
Thus, to find the potential energy, we have:

Therefore, the potential energy of the apple is 1.47 Joules.
ANSWER:
1.47 Joules
