A 300-gram weight is attached to a string which is hung in a hanging bar such that the weight is hung 20 cm from the ground and the weight is at rest. If the weight is to be swung like a pendulum, what is the weight's minimum gravitational potential energy in joules?
NOTE: Please use 9.8 meters per second squared for the measure of acceleration due to gravity.
