A student on a piano stool rotates freely with an angular speed of 3.05 rev/s . The student holds a 1.35 kg mass in each outstretched arm, 0.789 m from the axis of rotation. The combined moment of inertia of the student and the stool, ignoring the two masses, is 5.43 kg⋅m2 , a value that remains constant. a) As the student pulls his arms inward, his angular speed increases to 3.73 rev/s . How far are the masses from...

A student sits on a freely rotating stool holding two weights, each of which has a mass of 2.84kg. When his arms are extended horizontally, the weights are 0.970m from the axis of rotation and he rotates with an angular speed of 0.608rad/s. The moment of inertia of the student plus stool is 4.85kgm^2 and is assumed to be constant. The student pulls the weights inward horizontally to a position 0.200m from the rotation axis. Find the new angular speed...
