A disk with moment of inertia 9.15 × 10−3 kg∙m^2 initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 × 10−3 kg∙m^2 right above the disk’s center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity ?? about the same axis. There is no external torque acting on the system during the collision. Please compute the system’s quantities below. 1. Initial angular momentum ??...

A 200 g meter stick has a 50.0 g lump of clay stuck on it at the 10.0 cm mark. It is initially at rest on a level, frictionaless surface, lying along the y-axis with its 50.0 cm mark at the origin. A second 50.0 g lump of clay, initially moving at 1.20 m/s i, collides with the meter stick and sticks to it at the 90.0 cm mark. 1. What is the initial momentum of the system of the...
7) A turntable with moment of inertia IT = 0.042 kg m2 and radius R = 0.24 m is rotating with ω = 0.68 rad/s. A mouse of mass m = 0.053 kg is standing on the edge of the turntable. a) What are the total moment of inertia and the total angular momentum of this system? b) If the mouse walks towards the center of the turntable, does the angular velocity increase or decrease? Explain the answer conceptually. c)...
6. (BONUS) Two particles each with mass m = 0.4 kg, are fastened to each other, and to a rotation axis at 0, by the two thin rods, each of length d and mass M = 1.5 kg as shown below. The combination rotates around the rotation axis with angular speed w = 0.2 rad/s. The total moment of inertia of the system measured about O is 2.3 x 10-4 kg m?. (Hint: The moment of inertia of a thin...
The moment of inertia of the human body about an axis through
its center of mass is important in the application of biomechanics
to sports such as diving and gymnastics. We can measure the body's
moment of inertia in a particular position while a person remains
in that position on a horizontal turntable, with the bodys center
of mass on the turntable's rotational axis. The turntable with the
person on it is then accelerated from rest by a torque that...
Problem 3 A 60.0-kgrunner runs clockwise around the edge of a horizontal turntable mounted on a vertical, frictionless axis through its center. The runner's velocity relative to the ground has magnitude 2.00 m/s. The turntable is rotating in the opposite direction (counterclockwise) with an angular velocity of magnitude 0.300 rad/s relative to the ground. The radius of the turntable is 2.90 m, and its moment of inertia about the axis of rotation is 80.0 kg m2. Questions 4 and 5...
1, A 0.30 m radius automobile tire accelerates from rest at a constant angular acceleration of 0.758 rad/s2 for 2.23 s. What is its final angular speed in rad/s? 2. A turntable has a moment of inertia of 3.00 x 10-2 kg-m2 and spins freely on a frictionless bearing at 46 rev/min. A 1.11 kg ball of putty is dropped vertically onto the turntable and sticks at a point 0.100m from the center. What is the new rate of rotation...

A person with mass mp - 70 kg stands on a spinning platform disk with a radius of R = 2.1 m and mass mg 187 kg. The disk is initially spinning at a 2 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.7 m from the center). 1) What is the total moment of inertia of the system about the center of the disk when...
