Exam Problem I got wrong. Is it correct now?

  1. Jun 2, 2007 #1
    Hello, I had a statics exam last week and got part of the following problem wrong. I redid it just now and would like to know if my solution is correct. I'm having a little difficulty in understanding parallel and perpendicular components of a force.

    I'm interested in part (b).

    From my book it states that the projection of [tex]\vec{F}_parallel = \vec{F}\vec{u}[/tex]

    Isn't this just the dot product?

    NVM I figured it out
