2. Relevant equations

I am not really sure which equations would be relevant since my question seems to be more so concepts instead of numbers, so forgive me please :(

I am familiar with how to do just about all of this problem, I am simply baffled as to how I handle the idea of a voltage source and a current source both being there at the same time. I have solved such problems only with one voltage source, or one current source, but never one of each or two of one of them.

3. The attempt at a solution

I see that there is a .5mA source, and a 30mA source. One is going to shoot current one direction into the capacitor, and one is going to shoot. I say a 30mA source because I assume that I can simply turn the 150V source into a 30mA source in parallel with the 5K resistor. Is it really as simple as subtracting .5mA from 30mA and then simply having i be negative? And then once the switch closes, the components to the left of the switch get cut off?

All my other problems on this homework assignment seemed so straight forward, this one is such a curve ball *sigh*

Many thanks!! :)
