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.

What formulas do we need to use?
Use the formula KErot=1/2Iomega^2. Just make sure to make omega into units of rad/sec, which is abut 35.9.
