A mass on a spring is shown below. Let y(t) be the displacement of the spring as a function
of time t. Position A is the equilibrium position corresponding to y = 0. As was done in class, we are
taking the positive direction to be downward. The graph of the solution to an initial value problem
for this spring is shown. Answer the following questions about this system.
