A 30 mm - radius wheel is mounted on an axle OB of length 100 mm. The wheel rolls without sliding on the horizontal floor, and the axle is perpendicular to the plane of the wheel. Knowing that the system rotates about the y axis at a constant rate w = 2.4 rad/s determine (a) the angular velocity of the wheel, (b) the angular acceleration of the wheel, (c) the acceleration of Point C located at the highest point on the rim of the wheel.
