A solid body rotates with deceleration about a stationary axis with an angular deceleration 
where 
is its angular velocity. If at the initial moment of time its angular velocity was equal to 
then the mean angular velocity of the body averaged over the whole time of rotation till it comes to rest is 
where n is.
