An object's moment of inertia is 2.0 kg · m2. its angular velocity is increasing at the rate of 4.0 rad/s per second. what is the net torque on the object?

To solve the problem, we can use the equivalent of Newton's second law for rotational motions:

where
is the net torque acting on the object
I is the moment of inertia of the body
is the angular acceleration of the object.

Using the data of the problem:  and , we find the net torque acting on the object:
