The potential energy of a spring is 0.3 J when it is compressed 0.04 m to the left of its equilibrium position. At this point it comes to its leftmost position. What is its kinetic energy at this point?
A) -0.3 J
B) zero
C) 0.3 J
D) 375 N/m

At the leftmost position, the spring stops moving, hence its velocity becomes zero and so does its kinetic energy. Therefore, the answer is zero.

The Potential Energy of a Spring Is 0
