4. Cassette tapes store the tape around two wheels covered by a shell. When the tape is playing the tape unwinds from one wheel, passes over the tape head in the middle, and rewinds onto the other wheel. As the tape plays, it moves off one wheel and onto the other. This means that the tape is unwinding from a wheel at one radius and winding onto the other wheel with a different radius and the radii change as tape goes from one wheel to the other. At all times while playing the tape passes over the tape head at a constant speed of 4.75 cm/sec. a. At the beginning of a tape, the radius of one wheel is 2.5cm and the radius on the other side is 1.11 cm. What are the angular velocities of the two wheels
