Problem #4: When a 5 kg mass is attached to a spring whose constant is 20 N/m, it comes to rest in the equilibrium position. Starting at /= 0, a force equal to f(n) = 20e5r cos 2r is applied to the system. In the absence of damping, (a) find the position of the mass when t=. (b) what is the amplitude of vibrations after a very long time?
