**Question: Determining Torque from Rotational Motion** A 500-g wheel that has a moment of inertia of 0.015 kg·m² is initially turning at 30 revolutions per second. It coasts to rest after 163 revolutions. How large is the torque that slowed it down? **Answer Choices:** - A) 0.26 Nm - B) 0.09 Nm - C) 4.50 Nm - D) 0.04 Nm In this problem, we're tasked with calculating the torque that acted to slow a wheel during its motion. The wheel begins with a known initial angular velocity, comes to a rest, and completes a set number of revolutions in the process. Understanding these dynamics enables us to determine the magnitude of the torque applied.
