A person on a rotating stool with arms stretched out rotates at an angular speed of 5.00 rad/s. On bringing in his arms, the angular speed increases to 7.50 rad/s. By what factor does the moment of inertia change?

Physics
The combination of an applied force produces a constant total torque of 39.6 N.m on a wheel rotating about a fixed axis. The applied force acts for 5.3 s. During this time, the angular speed of the wheel increases from 0 to 9.8 rad/s. Determine the moment of inertia of the wheel.

physics
Starting from rest at t = 0 s, a wheel undergoes a constant angular acceleration. When t = 1.6 s, the angular velocity of the wheel is 5.5 rad/s. The acceleration continues until t = 17 s, when the acceleration abruptly changes to 0 rad/s2. Through what angle does the wheel ...

PHYSICS HELP PLEASE!!
A tangential force acts on the rim of a 2.0 kilogram disk-shaped wheel (0.50 m radius) and gives the wheel an angular acceleration of 4.8 rad/s^2. Neglect friction and find the magnitude of the force
