The equation for the displacement of a mass on a spring undergoing simple harmonic motion is given by x(t) = A cos(ωt), where A is the amplitude and ω is the angular frequency. What is the velocity of the mass as a function of time?

• v(t) = -Aω sin(ωt)

• v(t) = Aω sin(ωt)

• v(t) = -Aω cos(ωt)

• v(t) = Aω cos(ωt)
