A 6.52 grаm bullet is fired intо а 0.601 kg blоck аttached tо the end of a 0.670 m non uniform rod of mass 0.698 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about A is 0.0550 kg m2. If the angular speed of the system about A just after impact is 1.96 rad/s, what is the bullet’s speed (in m/s) just before the impact? Treat the block as a particle.
