Answer:
The value is
Explanation:
From the question we are told that
The mass is
The diameter is
The angular speed is
The mass of each of the blocks is
Generally the radius of the turntable is mathematically represented as
=>
=>
The moment of inertia of the turntable before the blocks fell is mathematically represented as
=>
=>
The moment of inertia of the turntable after the blocks fell is mathematically represented as
=>
=>
Generally from the law of angular momentum conservation
Here is the initial angular momentum of the turntable before the blocks fell which is mathematically represented as
and is the initial angular momentum of the turntable after the blocks fell which is mathematically represented as
So
=>
