cillator is described by

x(t) = (10 cm) sin[(1 s^-1)t]

What is the earliest time t ≥ 0 at which the

oscillator’s velocity is zero?

1. t = 1 s

2. We cannot say, since we are not given

vx(0).

3. t =π/2s

4. t = 0 s

5. t = π s

6. It will be zero at any time x is zero.

7. t = ∞; the velocity is never zero for any

ﬁnite time.

8. t = 2π s

9. t =π/4s

It's not 2,4,5, or 6... Can't figure it out.

Thank you.
