A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.765 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 36.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after...

A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.795 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 40.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after...

A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.735 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 32.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after...

A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.705 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 24.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after...

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...

A physics professor sits on a stool mounted to a low friction rotating platform while holding a 2.8 kg mass in each hand. When his arms are fully extended away from his body, the masses are each 1.15 m from the central vertical axis of rotation. A helpful student pushes on the masses as the professor begins spinning faster and faster until the professor rotates with an angular velocity of 0.9 rad/s. The moment of inertia of the professor and...

A student sits on a freely rotating stool holding two weights, each of mass 3.08 kg. When his arms are extended horizontally, the weights are 0.91 m from the axis of rotation and he rotates with an angular speed of 0.755 rad/s. The moment of inertia of the student plus stool is 3.08 kg·m2 and is assumed to be constant. The student pulls the weights inward horizontally to a position 0.294 m from the rotation axis. (a) Find the new...

A student sits on a freely rotating stool holding two weights, each of mass 4 kg.. When his arms are extended horizontally, the weights are 1.1 m from the axis of rotation and he rotates with an angular speed of 0.9 rad/s. The moment of inertia of the student plus stool is 3.0 kg-m2 and is assumed to be constant. The student pulls the weights inward horizontally to a position 0.4 m from the rotation axis. Find the new angular...

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...
