Question

Suppose you are sitting on a rotating stool holding a 2 kgmass

in each outstretched hand. If you suddenly drop the masses,will
your angular velocity increase, decrease, or stay the same?Please
Explain.

Answer 1

Answer:Increase

Step-by-step explanation:

Given

You are holding 2 kg mass in each outstreched hand

If the masses are dropped then Moment of inertia will decease by
`2mr^2`

Where m=2 kg

r=length of stretched arm

Since angular momentum is conserved therefore decrease in Moment of inertia will result in increase of angular velocity

as I
`\omega`=constant

I=Moment of inertia

`\omega`=angular velocity
