When a 3 kg mass is attached to a spring whose constant

When a 3 kg mass is attached to a spring whose constant is 75 N/m, it comes to rest in the equilibrium position. Starting at t= 0, a force equal to f(t) = 21e-o cos 4t is applied to the system. In the absence of damping, (a) find the position of the mass when t= T. (b) what is the amplitude of vibrations after a very long time? Problem #2(a): Round your answer to 4 decimals. Problem #2(b): Round your answer to 4 decimals.
