26PRACTICE PROBLEM
A new bicycle wheel has been developed and put on display. It is mounted on a rotating display platform. The wheel spins at 60.0 rad/s about its axle, while the platform rotates at 40.0 rad/s around a vertical axis. What is the resultant angular velocity of the wheel as observed by someone standing away from the platform? Find the magnitude and direction of the angular velocity.
