Angular Velocity of a hamster wheel

  1. Nov 4, 2008 #1
    1. The problem statement, all variables and given/known data
    A hamster runs in its wheel for 4.5 hours every night. If the wheel has a 6.8 cm radius and its average angular velocity is 3.0 radians per second, how far does the hamster run in one night?

    2. Relevant equations
    angular velocity = ang displacement / time

    3. The attempt at a solution
    3 = angular displacement / 16200 seconds
    angular displacement = 48600

    I know this isn't the correct solution but I can't find an equation to help me solve this for m.

    The problem is looking for a linear length as if the hamster's wheel was running along the ground (not an angular displacement). You should be able to easily convert knowing a parameter of the wheel (the given radius).
