FIGURE 6.9 FIGURE 6.9 shows a light string wound around a 2 kg pulley is attached to a 5 kg load. The height of the load is 2.5 m above the floor. When the load is released, the pulley starts to rotate and the load descends to the floor. The moment of inertia of the pulley is I = ¹ MR². 2 (a) (b) Determine the speed of the load just before it hits the floor. If the string suddenly snaps while the load is 1.5 m above the floor, explain qualitatively why the load would hit the floor with higher speed than that of (a). [ANS: 6.39 m s¹]

A cylinder has a cone removed from it. The cylinder and the conical hole have the same radius (2.06 meters) and height (4.56 meters). The cylinder has a density of 447 kg/m3. What is the rotational inertia of the cylinder with the cone removed in kg m2? You can set your origin at the tip of the cone, which is also the center of the base of the cylinder.
Two blocks with masses mj and m, are connected by a light string that passes over a pulley with rotational inertia I and radius R. The system is released from rest.

Two hangers are attached by a string to a vertically mounted pulley system as shown. One disk is bigger than the other, and the disks are attached to each other such that they rotate together. The axle has negligible friction. The mass of the large disk is 1200 grams and the radius is 11 cm. The mass of the small disk is 400 grams and the radius is 4 cm. The high hanger has a mass of 200 grams and starts 80 cm above the ground. The lower mass starts on the ground and has a mass of 100 grams. The hangers are released from rest. What is the velocity of the 200 gram hanger when it hits the floor?

Three children are riding on the edge of a merry-go-round that is a disk of mass 98 kg, radius 1.7 m, and is spinning at 19 rpm. The children have masses of 21.6 kg, 27.6 kg, and 35 kg.M = 98 kgm1 = 21.6 kgm2 = 27.6 kgm3 = 35 kgr = 1.7 mf = 19 rpm If the child who has a mass of 27.6 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm? f' =
A 33.2 kg boy and a 22.0 kg girl are standing at the edge of a 161 kg merry-go-round of radius 1.41 m that is currently rotating at 32.0 rpm. The two kids then walk inward toward the center of the merry-go-round; while the boy reaches the center, the girl stops halfway. Given their new positions, what is the new rate of rotation of the merry-go-round (in rpm)? For simplicity's sake, you may treat the kids as point masses and the merry-go-round as a flat disk. Hint: Figure 10.12 in the textbook provides a good refresher on the various moments of inertia!

A thin rod has a length of 0.369 m and rotates in a circle on a frictionless tabletop. The axis is perpendicular to the length of the rod at one of its ends. The rod has an angular velocity of 0.100 rad/s and a moment of inertia of 1.46 x 103 kg-m². A bug standing on the axis decides to crawl out to the other end of the rod. When the bug (whose mass is 5 x 10-3 kg) gets where it's going, what is the change in the angular velocity of the rod? idn ry C
