2. [l3 Points] - OSCOLPHYS16.P.020.WA. MOdU'B lq ASK YOUR TEACHER A rigid wheel of radius r rotates about an axis through the center and perpendicular to the plane of the wheel. Consider three points A, B, and C on the wheel, indicated by the small red circles. Location A is on the rim, locations B and C are on two different spokes of the wheel at a distance r/2 from the center. Consider the rotation of the wheel during a certain interval of time At. (a) Which of the following is true regarding the angular velocity? C) All three points have the same angular velocity as all three points have the same angular displacement 6 in the same time interval At. O Points B and C will have half the angular velocity of point A as they are at half the distance from the center of the wheel compared to A. O Points B and C will have twice the angular velocity of point A as they are at half the distance from the center of the wheel compared to A. (b) Which of the following is true regarding the tangential speed? C All three points have the same tangential speed as all three points have the same angular displacement 6 in the same time interval At. O Point A has a greater tangential speed as it is further away from the center of the wheel. O Points B and C will have a greater tangential speed as they are closer to the center. (c) Which of the following is true regarding centripetal acceleration? C All three points have the same centripetal acceleration as all three points have the same angular displacement 6 in the same time interval At. 0 Points B and C will have half the centripetal acceleration of point A as they are at half the distance from the center of the wheel compared to A. 0 Points B and C will have twice the centripetal acceleration of point A as they are at half the distance from the center of the wheel compared to A
