Horizontal Spring Displacement#

The displacement of a mass from its equilibrium position as it oscillates on a horizontal spring satisfies the equation \(x(t) = A\cos(\omega t + \phi_0)\).

Part 1(a)#

At \(t = 0\) s, if \(x = -A/{{ params.n}}\), There are the two possible values of \(\phi_0\) between 0 and 2\(\pi\) radians.
