One question about rotational speed

  1. Nov 20, 2007 #1
    1. The problem statement, all variables and given/known data


    A casino roulette wheel is set spinning with an initial angular speed of 15 rad/s. The ball is set spinning in the opposite direction with a constant angular speed of 20 rad/s as the
    "00" passed by. If friction makes the wheel slow down with an angular acceleration of 5 rad/s^2, How many times does the ball pass by the "00" after 3 seconds? ( Ignore the slowing down of the ball due to friction. )


    thx so much... could somebody help me to solve this quesion?
