(8%) Problem 12: A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 120 N/m and negligible mass. The mass undergoes simple harmonic motion when placed in vertical motion, with its position given as a function of time by y(t) = A cos(oot-o), with the positive y-axis pointing upward. At time t=0 the mass is observed to be passing through its equilibrium height with an upward speed of vo = 3.7 m/s.
