Can you answer both please and thank you

5 of 8 An undamped 1.27 kg horizontal spring oscillator has a spring constant of 27.9 N/m. While oscillating, it is found to have a speed of 3.74 m/s as it passes through its equilibrium position. What is its amplitude A of oscillation? A - m What is the oscillator's total mechanical energy Etor as it passes through a position that is 0.653 of the amplitude away from the equilibrium position? Etot =
