(25%) Problem 3: A mass m = 0.65 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 65 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(ot - *), with the positive y-axis pointing upward. At time t = 0 the mass is observed to be...
