Homework Help: Calculating angular displacement of clockhands

  1. Feb 24, 2010 #1
    1. The problem statement, all variables and given/known data
    What is the a.d of each of the following hands of a clock in 1h?
    the second and?
    the minute hand?
    the hour hand?


    2. Relevant equations
    That's what I'm looking for


    3. The attempt at a solution
    I'm having trouble getting it on paper, just a description of how one of you might crack this would be wonderful.


    thank you

    Going around a circle exactly once corresponds to [tex] 2 \pi [/tex] radians (of angular displacement). Going around the circle twice is twice that. Going half way around the circle is 1/2 that, and so on.

    So what's the angular displacement (i.e. how many radians are traversed) of a hand that goes around exactly once? One that goes around 60 times? And 60 x 60 times?
