CIRCULAR MOT 1. A test car moves at a constant speed around a circular track. If the car is 48.2 m from the track's center and has a centripetal acceleration of 8.05 m/s², what is the car's tangential speed? 2. A rope attaches a tire to an overhanging tree limb. A girl swinging on the tire has a centripetal acceleration of 3.0 m/s². If the length of the rope is 2.1 m, what is the girl's tangential speed? 3. As a young boy swings a yo-yo parallel to the ground and above his head, the yo-yo has a centripetal acceleration of 250 m/s². If the yo-yo's string is 0.50 m long, what is the yo-yo's tangential speed?
