DETAILS ZILLDIFFEQMODAP11 5.R.012, MY NOTES ASK YOUR TEACHER Amass 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. (Use g = 32 ft/s2 for the acceleration due to gravity.) (a) Find the equation of motion. (b) What are the amplitude, period, and frequency of the simple harmonic mation? amplitude ft period frequency cydes/s (c) At what times does the mass return to the point I foot below the equilibrium position? (Enter your answers as a comma-separated list. Let n represent an arbitrary Integer.) (d) At what times does the mass pass through the equilibrium position moving upward? (Let n represent an arbitrary Integer.) At what times does the mass pass through the equilibrium position moving downward? (letna represent arbitrary Integer.) (a) What is the velocity of the mass at -3/16 s? ft/s (f) At what times is the velocity zero? (Let a represent an arbitrary integer.)
