Given:
• Mass, m = 45.3 g
,
• Height, h = 31 cm
Let's find the potential energy.
To find the otential energy, apply the formula below:

Where:
PE is the potential energy in Joules
m is the mass in kg
g is acceleration due to gravity = 9.8 m/s²
h is the height in meters
• Convert the Mass from grams to kilograms:
Where 1 kg = 1000g

• Convert the height from cm to meters:
Where 1 m = 100 cm
![31\operatorname{cm}=\frac{31\operatorname{cm}}{100}=0.31m]()
Hence, we have:

Solving further, we would get:

Therefore, the potential energy is approxiamtely 0.138 Joules.
ANSWER:
0.138 Joules
