Circuit for simulation
I think the question is intended to specify the initial capacitor voltage Vo=5 at t=0 and initial inductor current Io=0 at t=0. Your circuit, as drawn on the right, seems to keep the voltage at 5 forever.
This is easy to fix with a Time-Controlled Switch that opens or closes at t=0. In fact, we'll use two of them: SW1 to disconnect the voltage source, and SW2 to connect the inductor.

The simulator produces the following plot:

Using time-controlled switches that switch at t=0 is a straightforward way both to think about and to specify initial conditions.
