A flywheel with the initial angular velocity `omega_0` decelerates due to the forces whose moment relative to the axis is proportional to the square root of its angular velocity. Find the mean angular velocity of the flywheel averaged over the total decleration time.

A particle rotates in a circle with angular speed omega_(0) . A retarding force decelerates it such that angular deceleration is always proportional to square root of angular velocity. Find the mean angular velocity of the particle averaged over the whole time of rotation.

A solid body rotates with deceleration about a stationary axis with an angular deceleration betapropsqrt(omega) , where omega is its angular velocity. Find the mean angular velocity of the body averaged over the whole time of rotation if at the initial moment of time its angular velocity was equal to omega_0 .
