    1. The problem statement, all variables and given/known data

    Im having trouble figuring out these two problems from my home work ive been working on them for 3 hours can anyone give me some insight?

    2. Relevant equations

    If the second problem is unclear, F(s) is (3s+4) divided by s(s+2).

    Attached is the home work

    Is the source a voltage or current? I suspect current ...

    source voltage is current, I can figure out the second problem by myself its just the first one is tricky and im a bit rusty.

    Sum currents at the input node. What do you get? Do it in the time domain first if you're not comfortable with transformed impedances.

    Then transform each term and solve for V(s), then inverse-transform for v(t). The i(t) and I(s) are obvious ...
