the answer is 4/3 + 27.7 cos(20t - 56deg). I was able to get the second part of the answer using super position. However, i don't know where the 4/3 is coming from.

what differential equation did you solve?
and how do you tell the initial condition?
if you don't know I'm still browsing the internet

curry · Answer

well, using super position, I first turned off the 2v voltage source. and then solved for v(t). then i turned off the current source and then solved for v(t) again. Then added these 2 v(t). That gives the second part of the answer.
