I managed to get it :) though for others who might be looking to solve this for their practice questions Convert Kb to Ka Ka = kw/Kb then just use an ice table with Ka=x^2/ 0.300M-x (x is small) and just -log[H3O+)

Ok... but I still don't get it... Is there a formula type thing that could help me?

Yes - if it is the same person answering it - it is me again! My question has STILL not been answered... How would I solve for upwards acceleration with this kind of image, assuming mass and force are given.

Physics
How would I go about calculating the acceleration of a mass being pulled up an inclined plane at an angle. Given - mass, and presumably angles So the object is being pulled up an angle at another angle.

But what about the second angle? There is another one besides theta that I don't know what to do about - but that explanation just helped alot with all the other problems!
