Extracted text: The semicircular disk of mass m = 2.3 kg is mounted in the light hoop of radius r= 235 mm and released from rest in position (a). Determine the angular velocity w of the hoop and the normal force N under the hoop as it passes position (b) after rotating through 180°. The hoop rolls without slipping. (a) (b) Answers: w = i rad/s N = i
