A DVD disc has a radius 6.0 cm and mass 28 gram. The moment of
inertia of the disc is ½ 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
While stops playing, it takes 2.5 minutes to stop rotating.
Calculate the angular deceleration.
[c] Also calculate the torque that stops the disc.
