A simple harmonic oscillator consists of a block of mass 45 g attached to a spring of spring constant 240 N/m, oscillating on a frictionless surface. If the block is displaced 3.5 cm from its equilibrium position and released so that its initial velocity is zero, what is the phase constant, φ , of its oscillations? Assume the block moves according to the equation x=xmaxcos(ωt+φ) .

The phase constant is arbitrary.
