An undamped 2.23-kg horizontal spring oscillator has a spring constant of 24.3 N/m. While oscillating, it is found to have a speed of 2.30 m/s as it passes through its equilibrium position. What is its amplitude of oscillation?
What is the oscillator\'s total mechanical energy as it passes through a position that is 0.785 of the amplitude away from the equilibrium position?
