Net torque probl

  1. Oct 23, 2005 #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)
    you already have the radius, so just find the force now

    What do you have to find the force? ill help you from there
