After all the metal has unwound from the roller, the student measures the radius R and the angular speed wo of the roller to be 25 cm and 20 rad/s respectively. Observed from the side, the roller rotates counterclockwise, as shown. A piece of clay of mass m strikes the very bottom edge of the roller with a horizontal velocity v = 4.0 m/s. The clay sticks to and rotates with the roller. The clay-roller system then rotates with a final angular velocity wi. (f) Is wi greater than, less than, or equal to wo? Justify your answer.

A uniform disk of mass 7.00m and radius 7.00r can rotate freely about its fixed center like a merry-go-round. A smaller uniform disk of mass m and radius r lies on top of the larger disk, concentric with it. Initially the two disks rotate together with an angular velocity of 14.0 rad/s. Then a slight disturbance causes the smaller disk to slide outward across the larger disk, until the outer edge of the smaller disk catches on the outer edge of the larger disk. Afterward, the two disks again rotate together (without further sliding). (a) What then is their angular velocity about the center of the larger disk? (b) What is the ratio K/K0 of the new kinetic energy of the two-disk system to the system's initial kinetic energy?

The figure shows a device that can be used to measure the speed of a bullet. The device consists of two rotating disks, separated by a distance of d = 0.922 m, and rotating with an angular speed of 90.8 rad/s. The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is = 0.360 rad. From these data, determine the speed of the bullet. Number i Bullet Units 19 kd + Motor
A merry-go-round of radius R = 2.6 m has a moment of inertia I = 223 kg × m2, and is rotating at 10 rpm. A child whose mass is 44 kg jumps onto the edge of the merry-go-round with a speed of 4.5 m/s in a direction tangential to the rim of the MGR, and in the direction in which it is spinning. The new angular speed (in rpm) of the merry-go-round is approximately
Earth has a mass of 5.97×1024 kg and a radius of 6.37×106 m. The period of Earth’s rotation is 24 hours (i.e., it rotates on its axis once every 24 hours).

Treat the Earth as a solid sphere, whose moment of inertia is I = 25 M R 2 . (a) What is the final rotation period, in hours? (b) What is the change in Earth’s rotational kinetic energy during this process? Give your answer in units of Joules.

Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. A star with a of mass of 2.0x1032 kg and radius 7.0x108 m is initially rotating at a rate of once every 30 days. The star collapses into a neutron star with the same mass but a new radius of 16,000 m. What is the angular speed of the star? (Give your answer in rotations per second.) Assume the star is a solid sphere: Isphere = 2/5 MR2. The Crab Nebula (shown below) formed from a nearby supernova (6000 light years away). Chinese astronomers observed the event in the year 1054 and since that time the nebula has been expanding into what it appears like today. The Crab Pulsar is a neutron star at the center of the nebula and the remains of the original supernova.
