In the figure, a 7.84 g bullet is fired into a 0.418 kg block attached to the end of a 0.972 m nonuniform rod of mass 0.453 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 0.0636 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 3.20 rad/s, what is the bullet's speed just before impact? Rod Block Bullet (a) Number Units kg-m^2 (b) Number Units m/s
