Two blocks are placed at the ends of a horizontal massless board, as in the drawing. The board is kept from rotating and rests on a support that serves as an axis of rotation. The block on the right has a mass of 5.4 kg. Determine the magnitude of the ang...

The Conservation of Angular Momentum will be conserved. (Hint: it states that the net external torque acting on the diver is zero.) Angular Momentum = moment of inertia x angular velocity (6.0) (1.2) = 12x 7.2 = 12x x = 0.6 kg·m^2
