QUESTION 2 A DVD disc has a radius 6.0 cm and mass 20 gram. The moment of inertia of the disc is 1/2 MR2 where M is the mass, R is the radius. While playing music, the angular 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. Attach File Browse Local Files Browse Content Collection Browse Dropbox
