What is the angular velocity of the combined object and mass after the drop?

**Please don't forget to state the combined mass after the
drop!!!**

Answer #1

An object with moment of inertia ?1 = 9.7 ? 10−4 ?? ∙ ?2 rotates
at a speed of 3.0 ???/?. A 20 ? mass with moment of inertia ?2 =
1.32 ? 10−6 ?? ∙ ?2 is dropped onto the rotating object at a
distance of 5.0 ?? from the center of mass. What is the angular
velocity of the combined object and mass after the drop?

A disk with moment of inertia I 1 rotates about a
frictionless , vertical axle with angular speed W 1 =12 rad/s . A
second disk, this one having moment of inertia l 2 =2l 1 and
initially not rotating , drops onto the first disk. Because of
friction between the surfaces , the two eventually reach the same
angular speed w 2 . What is the final angular velocity of the
combined system (in kg m/s^ 2 )

A turntable has a moment of inertia of 3.00 × 10−2 kg · m2 and
rotates freely on a frictionless support at 25.0 rev / min. A 0.600
kg putty ball is dropped vertically onto the turntable and glued at
a point 0.100 m from the center.
By what factor does the kinetic energy of the system change
after the putty is dropped onto the turntable?
TO.
0.91
B.
1.00
C.
0.83
D.
1.50

A solid disk rotates in the horizontal plane at an angular
velocity of .067rad/s with respect to an axis perpendicular to the
disk at its center. The moment of inertia of the disk is .10 kg*m2.
From above, sand is dropped straight down onto this rotating disk,
so that a think uniform ring has a mass of .5 kg. After all the
sand is in place, what is the angular velocity of the disk?

A solid disk rotates in the horizontal plane at an angular
velocity of 0.0663 rad/s with respect to an axis perpendicular to
the disk at its center. The moment of inertia of the disk is 0.162
kg·m2. From above, sand is dropped straight down onto this rotating
disk, so that a thin uniform ring of sand is formed at a distance
of 0.381 m from the axis. The sand in the ring has a mass of 0.497
kg. After all...

A turntable has a moment of inertia of 3.0 × 10−2
kg·m2 and spins freely on a frictionless bearing at 25
rev/min. A 0.60-kg ball of putty is dropped vertically on the
turntable and sticks at a point 0.10 m from the center. By what
factor does the kinetic energy of the system change after the putty
is dropped onto the turntable?
a. 1.0
b. 0.83
c. 1.5
d. 0.91

A circular table rotates in the x - y plane.
The table is the gray, solid cylinder. It has mass m and
radius R. The axis of rotation is the z-axis. The
direction of rotation is given by the arrow-heads. A hollow ring of
mass to be specified and radius R/2 is held at rest,
slightly above the table and dropped onto the rotating table. The
center of the ring is exactly in-line with the table’s axis of
rotation. There...

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 turntable with a moment of inertia of
5.4 × 10−3 kg. m2 reaches a constant rotational speed of 45 rpm
from rest in 6.30
seconds.
a. Find the number of revolutions the turntable made during this
time.
b. Determine the rotational work done by the applied torque for
increasing the
angular speed from zero to 45 rpm.
c. While rotating at a constant rotational speed of 45 rpm, a mouse
of 32-g was kept
15 cm from the center....
