(20%) Problem 5: A mass m = 1.77 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 85 N/m and negligible mass. The mass undergoes simple harmonic motion when placed in vertical motion. At time t = 0 the mass is observed to be at a distance d = 0.46 m below its equilibrium height with an upward speed of vo = 4.7 m/s. ▷ 33% Part (a) Determine the phase angle of the motion, in radians.
