A CD has a mass of 17.4 g and a radius of 6.01 cm. When inserted into a player, the CD starts from rest and accelerates to an angular velocity of 20.0 rad/s in 0.901 s. Assuming the CD is a uniform solid disk, determine the net torque acting on it.

  • physics - ,

    torque*radius=momentinertia*angular acceleration.

    I am not certain what your question about this is.
