What Is The Torque On The Object?

Question

An object's moment of inertia is 1.80 kg m^2. Its angular velocity is increasing at the rate of 4.00 rad/s^2.

1) What is the torque on the object?

Answer 1

Torque=Moment of inertia *Angular acceleration

Angular acceleration=4.00 rad/s^2

Moment of inertia=1.80 kg m^2

So:

T=1.80 kg m^2*4.00 rad/s^2

T=7.20 Nm
