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
The answer is D...it is a reflection over the x-axis
Elaborate? i will try to help!
Note that 1 meter = 100 centimeters, so 1.3 meters = 130 centimeters
It grew another 22 cm
130 + 22 = 152
152 cm is your answer
hope this helps
