231 Chapter Summary 2 sin (2t /4) N is applied to the system. Deter- mine the amplitude and frequency of the steady-state solution. 15. An 8-kg mass is attached to a spring hanging from the ceiling and allowed to come to rest. Assume that the spring constant is 40 N/m and the damping con- stant is 3 N-sec/m. At time t 0, an external force of 2 sin 2t cos 2t N is applied to the system. Deter- mine the amplitude and frequency of the steady- state solution. cond-order linear differential equations and pre- with constant coefficients. Much of the method Problem 15) I Got most of the problem except the frequency , the back of the book says 2/pi .
But I get something else.
