The spring-mass system in Problem 6 is modified by introduction of an external driving force, F(t). The resulting differential equation for the motion is d'y 2dy + 32y(t) = F(t). dt² Problem 9. For an external force, F(t) = 28 cos(3t), find the function y(t) that describes the motion of the mass. Does the motion remain bounded as t → +0? Explain your answer.

Question
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.
