# A mass–spring system is oscillating in simple harmonic motion. At the exact moment the mass passes through its equilibrium position, which of the following statements is true?

A mass–spring system is oscillating in simple harmonic motion. At the exact moment the mass passes through its equilibrium position, which of the following statements is true?

- **A.** Both its kinetic energy \( K \) and potential energy \( U \) are at a maximum.
- **B.** Its acceleration \( a \) is at a maximum and its velocity \( v \) is at a maximum.
- **C.** Its potential energy \( U \) is at a maximum and its velocity \( v \) is \( 0 \).
- **D.** Its kinetic energy \( K \) is at a maximum and its acceleration \( a \) is \( 0 \).
