The tape in a videotape cassette has a length L = 246 m. The tape plays for t = 2.0 h (Figure 9-41). As the tape starts, the full reel has an outer radius of about R = 49 mm, and an inner radius of about r = 14 mm. At some point during the play, both reels have the same angular speed. Calculate this angular speed in rad/s and rev/min.
