Problems 6 though 10 involve modelling the motion of an object attached to a spring. The function, y(t), denotes the displacement of the mass from the equilibrium position, and is a function of time, t. The velocity and acceleration are dy v(t) = y'(t) = dt dy a(t) = y"(t) = dt2 and respectively. All work, solutions and answers should be written in terms of t.

Question
The spring-mass system in Problem 6 is modified by introduction of a damping
force proportional to the velocity. The resulting differential equation for the
motion is
dy
dt
+c-

dt2
Problem 7. Find y(t) for c = 20, y(0) = 2, y'(0) = -1. Is the system overdamped,
underdamped, or critically damped.
