Answer:
Explanation:
The experimenter is rotating on his stool with angular velocity ω ( suppose )
His moment of inertia is I say
We are applying no torque from outside . therefore , the angular momentum will remain the same
Thus angular momentum L = I ω = constant
Thus we can say I₁ ω₁ = I₂ω₂ = constant
here I₁ is the initial moment of inertia and ω₁ is the initial angular velocity
Similarly I₂ is the final moment of inertia and ω₂ is the final angular velocity
When a been bag is dropped on his lap , his moment of inertia increases due to increase in mass
In the above equation, when moment of inertia increases , the angular velocity decreases . So its motion of rotation will decrease .
The guy that answered this is fake and he’s doing it for free points so
Just repost it and hope he doesn’t find it
We know, velocity = Displacement/Time
Therefore, Displacement= Velocity×Time
Here, displacement= 20×5 m = 100 m
Answer: 100 m
Centrifugal force is not a real force.
When you move around a curve, there IS a real force pulling you
around the curve. Since your body wants to go straight, it feels as if
there's a force trying to pull you away from the curve. But there isn't.
That feeling of a force is greater when your speed around the curve
is greater, or when the curve is tighter, i.e. smaller radius.
