Answer:
arc ? = 255°
Step-by-step explanation:
arc DB = 180° - 75° = 105°
arc ? = 360° - 105° = 255°
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
