A disc that has a mass of 2 kg and radius 10 cm is rotating at 5 radians per second. A hollow hoop of mass 1 kg and radius 8 cm that is stationary is dropped onto it, sticking to the disc. Solve for the resulting angular velocity they will share, in units of radian per second. Note moment of inertia for disc is (1/2)mr^2, and for the hoop is mr^2, and only the numerical answer needs to be typed in. *
