The tape in a videotape cassette has a total length 295 m and can play for 2 h. As the tape starts to play, the full reel has an outer radius of 40 mm and an inner radius of 14 mm. At some point during the play, both reels will have the same angular speed. What is this common angular speed? Answer in units of rad/s.

A merry-go-round full of kids initially has 5.33 kg-m^2 while maintaining an angular speed = 2.55 rad/s. Some kids move closer to the center of the merry-go-round increasing its speed to omega y = 3.00 rad/s What's the final inertia Ly? How do the final and initial kinetic energies compare: K_r > K_y K_d < k_1 or K_1 = K ? if they are different then where did the delta K go to or come from? A solid ball...
