Athin uniform cylindrical turntable of radius 3 m and mass 25 kg rotates in a horizontal plane with an initial angular speed of 7.9 rad/s. the turntable bearing is frictionless. a clump of clay of mass 12 kg is dropped onto the turntable and sticks at a point 1.1 m from the point of rotation.
find the angular speed of the clay and turntable.
a. 7.75532
b. 5.75699
c. 6.99693
d. 11.0707
e. 7.097
f. 8.15289
g. 8.35556
h. 4.96894
i. 8.6087
j. 9.56476

E). 7.097 rad/s

Explanation:

As we know that the turn table and the clay both are isolated from all external forces and torque so the angular momentum of the system must be conserved

so we will have

now plug in all data in it

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.
