    Hello, I am working on this problem

    However, I am getting a 900t term that the solution is lacking. I am wondering if what I did was wrong. My formula is consistent with the formula for a series RLC circuit that is critically damped.

    Check: What is the sign of dVC/dt at time t = 0+ ? Hint: In which direction is the initial current flowing?
