A uniform 2.0-kg cylinder of radius 0.15 m is suspended by two strings wrapped around it (Fig. 8.50). As the cylinder descends, the strings unwind from it. What is the acceleration of the center of mass of the cylinder? (Neglect the mass of the string.)
Answer to relevant QuestionsA planetary space probe is in the shape of a cylinder. To protect it from heat on one side (from the Sun’s rays), operators on the Earth put it into a “barbecue mode,” that is, they set it rotating about its long axis. ...A ball with a radius of 15 cm rolls on a level surface, and the translational speed of the center of mass is 0.25 m/s. What is the angular speed about the center of mass if the ball rolls without slipping? A uniform sphere and a uniform cylinder with the same mass and radius roll at the same velocity side by side on a level surface without slipping. If the sphere and the cylinder approach an inclined plane and roll up it ...What is the angular momentum of a 2.0-g particle moving counterclockwise (as viewed from above) with an angular speed of in a horizontal circle of radius 15 cm? (Give the magnitude and direction.) A billiard ball at rest is struck (bold arrow in Fig. 8.53) by a cue with an average force of 5.50 N lasting for 0.050 s. The cue contacts the ball’s surface so that the lever arm is half the radius of the ball, as shown. ...
