The potetial energy of a spring is 0.25 J when it is compressed 0.05m to the left of the equilibrium position. At this point it comes to its leftmost position. What is its kinetic energy when it returns to its equilibrium point?

a. zero
b. 0.25 J and the object is moving to the right.
c. -0.25 J and the object is moving to the left.
d. 0.25 J and the object is at rest.
