An object with inertia m = 1.5 kg is connected to a spring with spring constant k = 250 N/m and equilibrium position at x0 = 5 cm (for x > x0, the force is directed toward the origin). The object is initially at rest at position x = 10 cm. You grab the object and move it slowly to position x = 20 cm. After you finish moving it, you continue to hold the object at rest at its new position. How much work did you do on the object? I know the main equations but i just done know what to do. Please Help!
