Homework Help: Circular motion

  1. Sep 29, 2008 #1
    1. The problem statement, all variables and given/known data

    What is the angular speed of the tip of the minute hand on a clock, in rad/s?

    2. Relevant equations

    I thought the equations needed would be angular velocity= change of theta/change in time.

    3. The attempt at a solution

    I worked on this one and am sure it has a simple answer. I know that it moves 2pi radians in 3600 seconds. I figured that to be .001745 rad every second. When I put that answer in, it tells me to check it because I may have rounded incorrectly or used the wrong number of sig figs. Did I at least start this problem correctly?

    Generally counter-clockwise is taken as positive and clokwise as negative direction

    I tried it as negative but it still is telling me that is incorrect.
