Reported by, Jun 21, 2010
What were you trying to do when the problem occurred?
I was solving for time with a Change in Velocity equaling to -5sqaure root of 2.

What happened that you didn't expect?
I kept getting a different answer than you. I get the square root of 2 over 2, not 2 over square root of 2. Does the fraction reverse for some reason? 

Please provide any additional information below.
Thank you for any clarification that you can offer!

the 1st comment in the youtube video is over 2 years ago, where he addressed the error.
dont expect him to re do the whole video

Ok, I apologize. I didn't know he already addressed the error. I've been watching the videos off of the Khan Academy website, not Youtube, so I was not aware of the Youtube comment. I never expected him to redo the whole video. I just wanted to know whether the math I was doing was correct so that I could progress in the series. Thank you.
