The axle of a wheel is mounted on supports that rest ona rotating turn table as shown in the gure. The wheel has angular velocity !1 = 44:0 rad/s about its axle, and the turntable has angular velocity!2 = 35:0 rad/s about a vertical axis. What is the magnitude and direction of the angular velocity andangular acceleration vectors of the wheel?
