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.

I did 98^2/12 and its wrong what am i doing wrong?
You have to plug in 98 for the Ac in the equation Ac=v^2/r. R=radius=12 so multiply 12*58 and take the square root of the product.
Home free 9 minutes to go :D
