    1. The problem statement, all variables and given/known data

    a mouse is rinding on the rim of a 2.0kg wagon wheel that rotates freely in a horizontal plane at an angular frequency of 1.00 revs/sec. after riding there for a while, the mouse runs into the center, axis, of the wheel. the mass of mouse is 0.1kg and assume that all of the mass of the wheel is concentrated around the rim. what is the new angular frequency when the mouse reaches the axis?

    2. Relevant equations
    ok i know that [tex]\omega[/tex] is directly proportional to the freq. which is the angular frequency.

    3. The attempt at a solution
    using the equation for omega, 2(pi)/1 equals 6.28319. is that my new angular freq.? i dont understand what to use?
