An object is hung vertically from a spring with spring constant K=100N/M and stretching the spring by 30 cm. The spring is then stretched an additional 8 cm and release To oscillate. What is the mass of the object hanging from the spring? What is the angular frequency of the objects motion? What is the objects period of oscillation?

A spring is hanging vertically from a shelf. When a weight of mass 0.16 kg is hung from the spring, the spring stretches a distance 25 cm. That weight is then removed and a new weight of mass 0.30 kg is hung from the spring. This second weight is then lifted a distance of 1.8 cm and released. The weight oscillates up and down. What is the period of oscillation (in units of seconds)?
