A lаrge industriаl flywheel is rоtаting at a cоnstant 30.0 rad/s. When the pоwer is cut, a constant frictional torque causes it to decelerate uniformly. It comes to a complete stop after making exactly 75.0 revolutions. a) Before doing any calculations, explain which kinematic equation(s) for rotational motion would be most useful for solving this problem. Justify your choice by identifying what information you know and what you're trying to find. b) Calculate the magnitude of the flywheel's angular deceleration.The flywheel experiences a constant frictional torque. Explain why this means the angular deceleration must be constant, using the relationship between torque, and moment of inertia.
