Question: When a 2 kg mass is attached to a spring whose constant is 98 N/m, it comes to rest in the equilibrium position. Starting at

When a 2 kg mass is attached to a spring whose constant is 98 N/m, it comes to rest in the equilibrium position. Starting at t = 0, a force equal to f() = 10ecos 5t is applied to the system. In the absence of damping. (a) find the position of the mass when t = I. (b) what is the amplitude of vibrations after a very long time
