A standard cassette tape is positioned in a standard cassette player. Each and every side plays for 45 minutes. The two tape wheels of the cassette encompass a diameter of 2.0 cm when completely wound and fit onto two 1.0 cm diameter spindles in the player. Assume that a motor drives one spindle at constant angular speed of 0.90 rad/s and the other spindle are free to rotate at any angular speed. Determine the tape's thickness.
