Figure shows a student, sitting on a stool that can rotate freely about a vertical axis. The student, initially at rest, is holding a bicycle wheel whose rim is loaded with lead and whose moment of inertia is I about its central axis. The wheel is rotating at an angular speed omega_i from an overead perspective, the rotation is counter clockwise. The axis of the wheel point vertical, and the angular momentum vecL_i of the wheel points vertically upward. The student now inverts the wheel, as a result, the student and stool rotate about the stool axis. With what angular speed and direction does the student then rotate? (The moment of inertia of the student+stool+wheel system about the stool axis is I_0 )

A whel of M.I. = 1 kg-m^(2) is rotating at an angular speed of 40 rad/s. Due to friction on the axis, the wheel comes to rest in 10 minute. What is the angular momentum of the wheel in kg m^(2)//s two minutes before it comes to rest ?

A person sitting firmly over a rotating stool has his arms stretched. If he folds his arms, his angular momentum about the axis of rotation

A torque of 20 N-m is applied on a wheel initially at rest. Calculate the angular momentum of the wheel after 3 sec.

Kinetic energy of a wheel rotating about its central axis is E. Then kinetic energy of another wheel having twice the moment of inertia and half the angular momentum as that of the first wheel is
