Write the law of conservation of angular momentum! A wheel is rotating at angular velocity! Its rotation axis is vertical! On the axis of this wheel, another wheel is slowly mounted in the stoppage! And these two wheels rotate simultaneously at the same angular velocity! If the radius of the second wheel is equal to the radius of the first wheel, but its mass is half the mass of the first wheel, then calculate the combined velocity of both wheels?

Answer:
According to conservation of angular momentum I1ω = (I1 + I2) ω1 where I1 is M.I. of the original wheel and I2 that of the other wheel, ω is the initial angular speed and ω 1 is the common final angular speed.
