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

analytically derive the transient expressions for the following
1. the output voltage vot for t > 0
2. the power absorbed by each resistor and capacitor

2. Relevant equations

3. The attempt at a solution
I'm not sure where to start. Don't i need to know what vi(t) is?

I am new to circuit anaylsis too, but I am pretty sure you do, perhaps someone with more experience might advised other way.
Was no equation given being that both voltages are functions of time, t?

The only thing I can think of is that voltage can also be found by

$V = IR$
V(Voltage) = I(Current) x R(Resistance)

Write the KCL equation for that upper right node -- it will give you a differential equation to solve.
