Answer:r'=0.327 m
Step-by-step explanation:
Given
angular velocity
mass of objects
distance of objects from stool
Combined moment of inertia of stool and student
Now student pull off his hands so as to increase its speed to 3.60 rev/s
Initial moment of inertia of two masses
After Pulling off hands so that r' is the distance of masses from stool
Conserving angular momentum
