Question

Quizplus · Accepted Answer

C) Since Ahmed is at a greater distance from the axis of rotation, he covers more distance in the same amount of time, resulting in a greater tangential speed. E) Angular speed is the same for all points on a rigid rotating body, meaning both Jacques and Ahmed, despite being at different distances from the axis, rotate through the same angles in the same amount of time.
