RLC Circuit using Laplace transform
First, basic thing:

$$Vo(s) = I(s) \cdot X_C(s)$$

Replace Xc with its Laplace equivalent:

$$X_C = \dfrac{1}{sC}$$

Replace the formulas the first equation and you get the voltage function. You might need to massage the equation to simplify it.

Then you need to anti-transform: you can do it using the rules and tables.
