1.	A solid body rotates about a stationary axis with an angular deceleration β∝√ω where ω is its angular velocity. If at the initial moment of time, its angular velocity was equal to ω0, then the mean angular velocity of the body averaged over the whole time of rotation till it comes to rest is,
Answer» A solid body rotates about a stationary axis with an angular deceleration $β \propto \sqrt{ω}$ where $ω$ is its angular velocity. If at the initial moment of time, its angular velocity was equal to $ω_{0}$ , then the mean angular velocity of the body averaged over the whole time of rotation till it comes to rest is,
