question

One end of a horizontal, massless spring is attached to a wall. A mass of 0.30 kg is attached to the other end of the spring and rests on a table. The mass is displaced 0.030 m from its equilibrium position and released. It has a speed of 0.040 m/s as it passes through its equilibrium position. In the absence of friction, what is the total mechanical energy of the system?

choices

  1. 0.24 mJ
  2. 0.38 mJ
  3. 0.48 mJ
  4. 0.75 mJ
