A mass on the end of a spring bounces up and down as shown, after being released at time t = 0. [Figure 6.1] Which graph shows how the velocity varies with time?

A[Graph A: Velocity up starts at a positive maximum, then decreases to zero, becomes negative, and returns to zero, following a cosine curve.]

B[Graph B: Velocity up starts at zero, increases to a positive maximum, then decreases to zero, becomes negative, and returns to zero, following a sine curve.]

C[Graph C: Velocity up starts at zero, increases to a positive maximum, then decreases to zero, becomes negative, and returns to zero, with a higher frequency than B.]

D[Graph D: Velocity up starts at zero, increases to a positive maximum, then decreases to zero, becomes negative, and returns to zero, with a lower frequency than B.]

✓ Correct Answer

The correct answer is A: [Graph A: Velocity up starts at a positive maximum, then decreases to zero, becomes negative, and returns to zero, following a cosine curve.]
