An undamped 1.61-kg horizontal spring oscillator has a spring constant of 37.8 N/m. While oscillating, it is found to have a speed of 2.17 m/s as it passes through its equilibrium position. What is its amplitude of oscillation?
ANS=_____m?
What is the oscillator's total mechanical energy as it passes through a position that is 0.749 of the amplitude away from the equilibrium position?
ANS=_____J?
