Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

See Ch 3 Sheet 6 and extend the formulae from 2 to 3 vectors. See Ch 4 Sheet 5 for the component treatment of Newton's Law II.

my picture has 3 components but 4 forces written down. what does the fourth force mean?
Yes there are 3 vectors, but one of the them isn't parallel to either the x or y axis, so the 2 forces listed are representing the x and y components of that vector.
