Net Torque of a CD: Mass 17 g, Radius 6 cm, Acceleration 23 rad/s

[playboy2006]

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

I would like to clarify that the given information is not sufficient to determine the net torque acting on the CD. The given values of mass, radius, and angular velocity only allow us to calculate the moment of inertia and angular acceleration of the CD. To determine the net torque, we also need to know the external forces acting on the CD, such as the force applied by the CD player or any other factors affecting its rotation. Without this information, it is not possible to accurately determine the net torque acting on the CD.
