An undamped 1.60 kg horizontal spring oscillator has a spring constant of 22.4 N/m. While oscillating, it is found to have a speed of 3.90 m/s as it passes through its equilibrium position. @ Macmillan Learning What is its amplitude A of oscillation? A = 1.04 m What is the oscillator's total mechanical energy Eld as it passes through a position that is 0.753 of the amplitude away 19.03 from the equilibrium position? Incorrect
