Current Attempt in Progress In the figure, a 5.25 g bullet is fired into a 0.170 kg block attached to the end of a 0.698 m nonuniform rod of mass 0.572 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 0,0602 kg.m?. Treat the block as a particle. (a) What then is the rotational inertia of the block-rod-bullet system about point A? (b) If the angular speed of the system about A just after impact is 7.91 rad/s, what is the bullet's speed just before impact? Rod Block Bullet (a) Number Units (b) Number i Units
