Use torque, angular acceleration, and moment of inertia

Paper 1, Paper 2 5 marks Difficulty 3

Angular acceleration from torque

A rotating body in a wind-turbine blade audit has net torque \(18\,\text{N m}\) and moment of inertia \(3\,\text{kg m}^{2}\). Calculate the angular acceleration. Read the diagram before calculating the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.
