An object is attached to a vertical spring and bobs up and down between points A and B.Where is the object located when its elastic potential energy is a minimum?
A)at either A or B
B)midway between A and B
C)one-third of the way between A and B
D)one-fourth of the way between A and B
E)at none of the above points

The elastic potential energy in a spring is minimum when the spring is neither stretched nor compressed, which occurs at the equilibrium position. This position is midway between the two extremes of the motion (points A and B), where the spring force balances the gravitational force.
