Homework Help: Dynamics - Unbalanced Force - Probably Very Easy

  1. Jun 1, 2005 #1
    Hi again,

    we're starting dynamics now and the example problem in the book is very confusing, I don't understand how they got their answer.

    tanΘ = opposite/adjacent
    = 5.0 N/7.0 N
    = 36 degrees

    It must be very simple, but I can't get 36 degrees when I try it.

    What do I need to input into my calculator to recieve this answer?

    Oops! I figured it out, I hadn't put my calculator into degree mode!

    Good to hear it was only something simple. I used to get stuck for ages wondering why my answers were coming out funny.
