Simple Harmonic Motion Displacement Equation

Question

Which of the following equations represents the displacement of an object in simple harmonic motion (SHM) as a function of time?

Accepted Answer

$$x(t) = A \cos(\omega t + \phi)$$

Answer

$$a(t) = -A \omega^2 \cos(\omega t + \phi)$$

Answer

$$v(t) = A \omega \sin(\omega t + \phi)$$

Answer

$$F(t) = -kx(t)$$
