Concept #1: Simple Harmonic Motion of Vertical Springs

Practice: A spring with spring constant 15 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 6.0 cm and released. If the ball makes 30 oscillations in 20 s, what are its (a) mass and (b) maximum speed?

Practice: A chair of mass 30 kg on top of a spring oscillates with a period of 2s. (a) Find the spring’s force constant. You place an object on top of the chair, and it now oscillates with a period of 3s. (b) Find the object’s mass.
