Label the length of the string between the top of the cylinder and the rotating stopper, the mass of the rubber stopper and hanging washers, and the velocity and acceleration factors of the stopper. 2) Gravity pulls down word on the stopper and assume that it is approximately parallel to the ground. Draw a new Sideview picture with the stopper moving clearly horizontal. 3)Draw free body diagram of the forces on the stopper in the force is on the hanging washers while the stopper is moving horizontally. Assign symbols to all the forces and define what they represent next year diagrams. It is useful to put the fourth specters on a separate coordinate system for each object. 4)For each force diagram for the stopper and for the washer right down newtons second law in both the ex and Y directions.
