Answer to Question #122410 in Physics for jacob

Question

In the figure, a 7.21 g bullet is fired into a 0.738 kg block attached to the end of a 0.602 m nonuniform rod of mass 0.822 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 0.0530 kg·m2. 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 5.93 rad/s, what is the bullet's speed just before impact?
