A 5 kg sticky mass is moving at a constant 2 m/s towards a rod that's fixed on its right side, acting as its axis of rotation. The rod has a rotational inertia of 20 kgm2. The sticky mass collides and attaches itself to the rod 0.3 m away from its axis of rotation. The rotational inertia of the rod after the collision is (20 + mr2) where m is 5 kg and r is the distance away from the axis of rotation that the mass attaches itself to the rod. Calculate the angular velocity of the rod and mass after the collision.
