Chapter 5, Problem 5.1.134(choose chapter or problem)
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. (a) Find the equation of motion. (b) What are the amplitude, period, and frequency of the simple harmonic motion? (c) At what times does the mass return to the point 1 foot below the equilibrium position? (d) At what times does the mass pass through the equilibrium position moving upward? Moving downward? (e) What is the velocity of the mass at ? (f) At what times is the velocity zero?
