Homework Help: Need help on Net External force

  1. Nov 9, 2009 #1
    A dog pulls on a pillow with a force of 7.9 N at an angle if 28.3 degrees above the horizontal

    [tex]\vec{F}_{net} = \Sigma \vec{F} = m \vec{a}[/tex]

    A) What is the x component of this force?
    answer in units of N.

    B) What is the y component of this force?
    answer in units of N.

    help pls i cant find a way.
    and im not a drawing kind of guy. thanks for any help like step by step

    First, before we can even help you, you need to show your attempt at the solution. Second, whether or not you're a "drawing kind of guy", you'll have a difficult time doing a lot of physics problems without first drawing a free-body diagram. So, draw a free-body diagram and then show your attempt at a solution!

    Show what you tried so people can help with what you are misunderstanding.

    If you have no idea at least try to draw a picture for yourself, it will help.

    You have a vector and you have its direction, now you just need to break it into an

    x and y component. The x an y form the legs of a triangle and the Net vector is the

    hypotenuse. See what you get.
