A hoop has mass and radius of 4 kg and 0.37 m, respectively. The hoop start from rest and has a constant angular acceleration with respect to a rotational axis that is perpendicular to the plane of the hoop at its center. The hoop turns through an angle of 16 rad in 6.3 s. Find the net external torque that acts on the hoop.
