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 finished my lab 2 assignment and graded it. But when I click on the lab 2 assignment again, there is no record showing I've finished the assignment? I just want to make sure if that's normal.
I know the formula I am putting in for #6 is correct and its saying its incorrect, maybe I am messing up the format but I've tried it a thousand different ways and I was able to correctly enter the formula for #7 which is similar. So I am stumped. Is there an error on this question?

for question one i am putting that v= v_0 + a*t is that in the wrong format or just wrong?
v= v_0 + a*t is the right formula, you are just putting it in wrong. The instructions say to use v0 not v_0
