Multiple ChoiceWhich of the following describes the motion of a mass attached to a horizontal spring undergoing simple harmonic motion?545views
Multiple ChoiceA pendulum in the service shaft of a building is used by a physics class for experiments. The shaft is dark, and the top of the pendulum cannot be seen. The bob of the pendulum is visible, and it is observed to complete 13 oscillations in 114 seconds. Assume the motion is simple harmonic. What is the period of the pendulum?524views
