The displacement from rest of a mass attached to a spring satisfies the simple harmonic motion equation x ( t ) = A cos ( ω t − ϕ ) , where ϕ is a phase constant, ω is the angular frequency, and A is the amplitude. Find the average velocity, the average speed (magnitude of velocity), the average displacement, and the average distance from rest (magnitude of displacement) of the mass.
