A wheel of moment of inertia `0.10 kg-m^2` is rotating about a shaft at an angular speed o 160 rev/minute. A second wheel is set into rotation at 300 rev/minute and is coupled to the same shaft so that both the wheels finally rotate with as common angular speed of 200 rev/minute. Find the moment of inertia o the second wheel.

Explanation

(a) `4.00xx10^(-2)kg*m^(2)`, (b) -3.07 J
