A disc is rotaing with an angular velocity `omega_(0)`. A constant retarding torque is applied on it to stop the disc. The angular velocity becomes `(omega_(0))/(2)` after n rotations. How many more rotations will it make before coming to rest ?

A disc is rotating with angular velocity omega . If a child sits on it, what is conserved?

A heavy disc is rotating with uniform angular velocity omega about its own axis. A piece of wax sticks to it. The angular velocity of the disc will

When a ceiling fan is switched off, its angular velocity reduces to 50% while it makes 36 rotations. How many more rotations will it make before coming to rest?(Assume uniform angular retardation)

A ceiling fan is rotating about its own axis with uniform angular velocity omega . The electric current is switched off then due to constant opposing torque is its angular velocity is reduced to (2 omega)/3 as it completes 30 rotations. The number of rotations further it makes before coming to rest is

A disc rotates with angular velocity omega and kinetic energy E . Then its angular momentum

A circular disc is rotating about its own axis at a uniform angular velocity omega . The disc is subjected to uniform angular retardation by which its angular velocity is decreased to omega/2 during 120 rotations. The number of rotations further made by it before coming to rest is

A flywheel rotates about an axis. Due to friction at the axis, it experiences an angular retardation proportional to its angular velocity. If its angular velocity falls to half while it makes n rotations, how many more rotations will it make before coming to rest?

A fly wheel rotates about an axis. Due to friction at the axis, it experiences an angular retardation proportional to its angular velocity. If its angular velocity falls to one fourth while it makes n rotations, how many roations will it make before coming to rest ?
