Q2. A rubber stopper, which has a mass of m= 14.5 grams, is tied to the end of a string which is threaded through a glass tube. You then spin the rubber stopper about your head in a horizontal circle as shown to the right. The stopper sags ß = 18.0° below the horizontal as shown and the distance from the top of the tube to the stopper is L = 1.25 m. a. Draw the freebody diagram showing each of the forces acting on the rubber stopper. M b. What will be the magnitude of the centripetal force acting on the stopper? c. What is the speed of the stopper?
