(11%) Problem 2: A mass m= 1.5 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 125 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(or-p), with the positive y-axis pointing upward. At time t=0 the mass is observed to be at a distance d= 0.35 m below its equilibrium height with an upward speed of vo 4 m/s. Merill, Abbir-ampg malum.
