Unformatted text preview: r > R/ 2. Calculate the moment of inertia about an axis through the center and perpendicular to the disk, expressed solely in terms of the total mass M and radius R . Problem 8 A block is on a horizontal table and attached to a string that passes over a pulley and attached to another mass that hangs over the table and is free to fall. The pulley is a solid disk of radius R . The mass of the disk, the block, and the hanging mass are all the same and equal to m . Assume the force of static friction between the block and the table is small enough so that the block slides and experiences kinetic friction with coecient k . (a) Find the tension in the string on both sides of the pulley. (They are not the same!) (b) What is the acceleration of the hanging mass? 1...
