Question

A uniform cylindrical turntable of radius 1.70 m and mass 29.1
kg rotates counterclockwise in a horizontal plane with an initial
angular speed of 4*π* rad/s. The fixed turntable bearing is
frictionless. A lump of clay of mass 2.31 kg and negligible size is
dropped onto the turntable from a small distance above it and
immediately sticks to the turntable at a point 1.60 m to the east
of the axis.

(a) Find the final angular speed of the clay and turntable.

magnitude=_______ | rad/s |

(b) Is mechanical energy of the turntable-clay system constant in this process?

What, if any, is the change in internal energy?

=________ J

(c) Is momentum of the system constant in this process?

What, if any, is the amount of impulse imparted by the bearing?

magnitude=______ | kg · m/s |

A uniform cylindrical turntable of radius 2.00 m and mass 31.2
kg rotates counterclockwise in a horizontal plane with an initial
angular speed of 4? rad/s. The fixed turntable bearing is
frictionless. A lump of clay of mass 2.42 kg and negligible size is
dropped onto the turntable from a small distance above it and

A turntable has moment of inertia 1 kg m2 and rotates
with angular speed of 3 rad/s. A small heavy mass (point particle)
of mass 5 kg is placed on the turn table at 2 m from the axis of
rotation of the turn table. What is the final rotational velocity
of the system? Give your result in rad/s to three significant
figures.

A uniform disk of mass M and radius R is initially rotating
freely about its central axis with an angular speed of ω, and a
piece of clay of mass m is thrown toward the rim of the disk with a
velocity v, tangent to the rim of the disk as shown. The clay
sticks to the rim of the disk, and the disk stops rotating.

clay-disk system...

A large wooden turntable in the shape of a flat uniform disk has
a radius of 1.65 m and a total mass of 135 kg. The turntable is
initially rotating at 3.10 rad/s about a vertical axis through its
center. Suddenly, a 65.5-kg parachutist makes a soft landing on the
turntable at a point near the outer edge.
(a) Find the angular speed of the turntable after the
parachutist lands. (Assume that you can treat the parachutist as a
particle.)...

Each of the following objects has a radius of 0.209 m and a mass
of 2.31 kg, and each rotates about an axis through its center (as
in this table) with an angular speed of 36.0 rad/s. Find the
magnitude of the angular momentum of each object. (a) a hoop kg ·
m2/s (b) a solid cylinder kg · m2/s (c) a solid sphere kg · m2/s
(d) a hollow spherical shell kg · m2/s

A 65.0-kg woman stands at the rim of a horizontal turntable
having a moment of inertia of 460 kg · m2 and a radius of 2.00 m.
The turntable is initially at rest and is free to rotate about a
frictionless vertical axle through its center. The woman then
starts walking around the rim clockwise (as viewed from above the
system) at a constant speed of 1.50 m/s relative to the Earth.
(a) In what direction does the turntable rotate?...

A 50 kg woman stands at the rim of a horizontal turntable having
a moment of inertia of 560 kg·m2 and a radius of 2.0 m.
The turntable is initially at rest and is free to rotate about a
frictionless vertical axle through its center. The woman then
starts walking around the rim clockwise (as viewed from above the
system) at a constant speed of 1.5 m/s relative to the Earth.
(a) In what direction and with what angular speed...

A cylindrical rod of length 2.0 m, radius 0.5 m, and mass 1.5 kg
has two spheres attached on its ends. The centers of the spheres
are 1.0 m from the center of the rod. The mass of each sphere is
0.66 kg. The rod is capable of rotating about an axis passing
through its center and perpendicular to the plane of the page, but
the set up is stationary to begin with. A small mass of value 0.19
