A 20lb weight is suspended from the end of a vertical spring of negligible mass. This much weight stretches the spring by 6nches. It is then pulled 2 inches down and released.
How is it to determine the y(t) and v(t)?
Suppose that the spring weight is pulled 3 inches down andgiven an initial speed of 2 ft/s downward. Determine the positionand speed of the weight as a function of time.
