Please do not answer unless you are sure it is correct. thank you.

" A mass hanging from a vertical spring is somewhat more complicated than a mass attached to a horizontal spring because the gravitational force acts along the direction of motion. Therefore, the restoring force of the oscillations is not provided by the spring force alone, but by the net force resulting from both the spring force and the gravitational force. Ultimately, however, the physical quantities of motion (position, velocity, and acceleration) for a vertical mass on a spring exhibit the same oscillations as a horizontal mass on a spring. TEMNO som A 100 g mass hangs from a vertical spring as shown in the picture. The measuring stick shows us the vertical y position of the bottom of the spring with the origin (y = 0) at the op of the spring. Note that the positive y direction is downward. The 100 g mass is at rest at the position shown (y = 50 cm). The dash osition shown (y = 50 cm). The dashed line in the picture (y = 30 cm) indicates the unstretched resting length of the spring. The mass is pulled down 9 cm, stretching the bottom of the spring to y = 59 cm, and then released so that it begins oscillating. ... ... 1. What are the equilibrium position and amplitude of the oscillations? YE A= 2. Is the spring force equal to zero at the equilibrium point? Explain why or why not. This answer has not been graded yet.
