PHY 121 Blog help

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.

Ch4_2 #4

See Ch 4 Sheet 27. Replace the block by the land rover and see Sheet 28.
Warning! To simply use the solution on Sheet 28 to get the coefficient of friction will work for you but would be a silly short cut. You will be required in the exam to understand the equations on Sheet 26, so study Example 4.4!
