A DVD disc has a radius 6.0 cm and mass 20 gram. The moment of inertia of the disc is % MR? where M is the mass. R is the radius. While playing music, the angula velocity of the DVD. is 160.0 rad/s. Calculate [a] the angular momentum of the disc (b] While stops playing, it takes 2.5 minutes to stop rotating. Calculate the angular deceleration. [c) Also calculate the torque that stops the disc, Collection Browse Dropbox
