Asmall blob of putty of mass m falls from the ceiling and lands on the outer rim of a turntable of radius r and moment of inertia i0 that is rotating freely with angular speed ω0 about its vertical fixed-symmetry axis. (use any variable or symbol stated above as necessary.) what is the postcollision angular speed of the turntable-putty system?

Explanation:

Mass = m

Radius of turn table = R

Initial moment off inertia of table = Io

Initial angular velocity is =ωo

As we know that if there is no any external torque on the system then its angular momentum will remain conserve .

So initial angular momentum of table = Io x ωo

Now lets take speed of the mass and turn table system will become ω

Final inertia of system is I

Final linear momentum

it would be c. predictability
