A fan of moment of inertia 0.6kgm^(2) is moving with a speed of 0.5 r.p.s. The angular momentum of the fan is

A solid cylinder of moment of inertia 0.625 kgm^(2) , rotates about its axis with an angular speed of 200 rad/s. What is the magnitude of angular momentum of the cylinder about its axis ?

A wheel of moment of inertia 5xx10^(-3) kg m^(2) is making 20 revolutions per second. If it is stopped in 20 s, then its angular retardation would be

A student sits on a stool that is free to rotate about a vertical axis. He holds out his arms horizontally, with a 4-kg weight in each hand. The stool is set in rotation with angular speed of 0.5 revolution per second. Calcualate the angular speed of the student is 90 cm and his rotational inertia is 7kg m^(2) . [Hint: Use conservation principle]

A fly wheel of moment of inertia 4xx10^(-3)kgm^(2) is makign 10 revolution per second. The torque required to stop it in 5 second is:

Moment of inertia of a body is 1 kg m2. If the body makes 2 revolutions per second, when its angular momentum is
