Question

I am a bit of an overachiever, and I've developed a habit of reviewing subjects during the summer before I take them in the new year. I was just looking through the posts on this site for review, when a certain physics question caught my attention. It was posted by "bobby on Friday, August 3, 2007 at 7:18pm." It was on page 10, the last time I checked. Now, the last part of the question was left unanswered, so I went and solved it myself. However, because no answer was given, I do not know if mine is correct. So, did anyone do part c) of this problem and get 3.1 seconds as their answer? Thank you.

I got 3 seconds.

Fantastic!! Now, did anyone else get a different answer?
