A rigid body rotating about a fixed axis with uniform angular retardation completes 33 rotations before its angular velocity is reduced to half of its initial value.Find the number of rotations made by the body further before it comes to rest.

A body moving with uniform retardation covers 3 km before its speed is reduced to half of its initial value. It comes to rest in another distance of

Angular momentum of a rigid body rotating about a fixed Axis with angular velocity vec omega

A circular disc is rotating about its own axis at uniform rate completes 30 rotations in one minute.The angular velocity of disc in rad s^(-1) is

A rigid body is free to rotate about an axis. Can the body have non-zero angulalr acceleration of an instant when its angular velocity is zero?

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 stationary wheel starts rotating about its own axis at an angular acceleration 5.5 rad//s^(2) . To acquire an angular velocity 420 revolutions per minute , the number of rotations made by the wheel 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?

The motor of an engine is rotating about its axis with an angular velocity of 100 rpm. It comes to rest in 15s , after being switched off. If angular deceleration is constant, what is the number to revolutions made by it before coming to rest ?

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

The motor of an engine is rotating about its axis with angular velocity of 120 rpm . It comes to rest in 10s , after being switched off. Assuming constant deceleration, calculate the number of revolutions made by it before coming to rest.
