A cubical block of side \( 30 \mathrm{~cm} \) is moving with velocity \( 2 \mathrm{~ms}^{-1} \) on a smooth horizontal surface. The surface has
\( \mathrm{P} \)
a bump at a point \( O \) as shown in figure. The angular velocity (in rad/s) of the block immediately after it hits the bump, is:
(1) 13.3
(2) 5.0
(3) 9.4
(4) 6.7
