Problem #7: When a 3 kg mass is attached to a spring whose constant is 147 N/m, it comes to rest in the equilibrium position. Starting at t=0, a force equal to f(t) cos 5t is applied to the system. In the absence of damping, = 18e -60 (a) find the position of the mass when t= T. (b) what is the amplitude of vibrations after a very long time? Problem #7(a): Round your answer to 4 decimals. Problem #7(b): Round your answer to 4 decimals. Problem #7: When a 3 kg mass is attached to a spring whose constant is 147 N/m, it comes to rest in the equilibrium position.
