# Question: Write the general equation of motion for a mass that

Write the general equation of motion for a mass that is on a horizontal frictionless surface and is connected to a spring at equilibrium

(a) If the mass is initially pulled in the axis from the spring (stretched) and released, and

(b) If the mass is pushed in the axis toward the spring (compressed) and released.
