I need help finding the initial displacement x(0) in meters,

the initial velocity x'(0) m/s, the spring constant k in N/m (kg/s²), the angular velocity in Hz, c₁ and c₂ in the equation for x, and the frequency f in Hz for this problem.

A 200g mass stretches a spring 5cm. The mass is released from rest from a position 10cm below the equilibrium position. Assume the positive direction is downward.
