2. Homework Equations / 3. The Attempt at a Solution
Unfortunately, I have no clue where to start. :( I should add that due to extenuating circumstances I've missed quite a bit of physics instruction, that probably would have been necessary to know; my requests for help from the professor yielded no result, as he seems to think the problems are "easy" enough to just work it out - but that's not possible if one isn't even sure of which equations to start with, and/or why they should be used.
Any and all help would be appreciated. Thanks.
