As the cord unravels from the wheels inner hub, the angular velocity of the outer hub = 2 rad/s. Determine the magnitudes of the the velocities at points A and B. The diagram has a picture of a large outer circle with a smaller inner circle, and a cord is attached to the inner circle and also attacked to a wall. The cord unravels and the angular velocity = 2 rad/s. The inner radius = 2 in, and the outer radius = 5 inches. The have the velocities starting from the center and pointing straight down, and staight to the left.
