The following table lists data for the speed and radius of three examples of uniform circular motion. Find the magnitude of the centripetal acceleration for each example. Radius Speed Example I 0.52m 19mm Example 2 Innitely large 34mm Example 3 2.8m 2.4mm Multiple-Concept Example 7 deals with the concepts that are important in this problem. A penny is placed at the outer edge of a disk (radius = 0.174 m) that rotates about an axis perpendicular to the plane of the disk at its center. The period of the rotation is 1.60 s. Find the minimum coefficient of friction necessary to allow the penny to rotate along with the disk.A "swing" ride at a carnival consists of chairs that are swung in a circle by 1?.5 m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 142 kg. {3} Determine the tension in the cable attached to the chair. lb} Find the speed of the chair. A woman is riding a Jet Ski at a speed of 21 m/'s and notices a seawall straight ahead. The farthest she can lean the craft in order to make a turn is 21% This situation is like that of a car on a curve that is banked at an angle of 21% If she tries to make the turn without slowing down, what is the minimum distance from the seawall that she can begin making her turn and still avoid a crash?Two satellites are in circular orbits around the earth. The orbit for satellite A is at a height of 495 km above the earth's surface, while that for satellite B is at a height of 774 km. Find the orbital speed for (a) satellite A and (b) satellite B
