Homework Help: Units Question

  1. Nov 13, 2005 #1
    I have a question that says "the angular acceleration is 1.25p r/s2." What does the "p" mean?

    Could it be pico? It might help to know the context.

    ...the questions follow after that (such as what is the angular speed at 2 sec), but when I answered them without regard to the "p," I got the answers wrong. This makes me think the "p" actually means something, I just don't know what.

    Thanks again.

    Could this be momentum? I don't know why it would be here, but that's the only thing I can think of...

    Edit: Sorry about that. I found out it represented pi. I don't know why it was written only with a p in that particular question (since it was written as "pi" throughout the others), but that's how it goes.

    Thanks again.
