Homework Help: Spring Scale, the force will the scale read?

  1. May 31, 2009 #1
    1. The problem statement, all variables and given/known data
    A 3.0 kg object rotates on a circular platform 1.5 m from the center. The tangential velocity of the object is 10.0 m/s. If the mass is attached to a spring scale, what force will the scale read?

    2. Relevant equations
    Sorry I have no idea.

    3. The attempt at a solution
    I could not even attempt or figure out, sorry.

    Start by looking up centripetal force and if you still get stuck then come back but show what you have tried.If you need to come back will you please clarify your question?

    Oh ok thanks! I forgot about centripetal force, I figured it out.

    Sorry I'm new to these forums, so it's all about attempting before asking.
