The potential energy (PE) of an object can be calculated using the formula:

PE = mgh

where:
m = mass of the object (in kg)
g = acceleration due to gravity (approximately 9.8 m/s² on Earth)
h = height above the ground (in m)

Given in the problem:
m = 0.45 kg
g = 9.8 m/s²
h = 1.2 m

Substituting these values into the formula gives:

PE = 0.45 kg * 9.8 m/s² * 1.2 m = 5.29 J

So, the potential energy of the ball is 5.29 Joules. The correct answer is B.
