Amass weighing 12 pounds stretches a spring 2 feet. The mass is initially released from a point

Question:

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.

(a) Find the equation of motion.

(b) What are the amplitude, period, and frequency of the simple harmonic motion?

(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 t = 3π/16 s?

(f ) At what times is the velocity zero?
