Question

A mass weighing 12 pounds stretches a spring 2 feet. The mass is initially released from a point 1 foot below the equilibrium position with an upward velocity of 4 ft/s.
- Find the equation of motion.
- What are the amplitude, period, and frequency of the simple harmonic motion?
- At what times does the mass return to the point 1 foot below the equilibrium position?
- What is the velocity of the mass at t = 3π/16 s ?
- At what times is the velocity zero?

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.
