Net torque probl

  • #1
A CD has a mass of 17 g and a radius of 6.0 cm. When inserted into a player, the CD starts from rest and accelerates to an angular velocity of 23 rad/s in 0.36 s. Assuming the CD is a uniform solid disk, determine the net torque acting on it.



I found the inertia which is 306 and got the angular acceleration which is 52.5i think those are the right values

im stuck please help

torque=(mag of force)(radius of lever arm)
