In the figure, a 7.50 g bullet is fired into a 0.476 kg block attached to the end of a 0.639 m nonuniform rod of mass 0.893 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 0.0432 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 5.35 rad/s, what is the bullet's speed just before impact? Rod Block Bullet (a) Number i Units (b) Number UnitsIn the gure, a small 0.344 kg block slides down a frictionless surface through height h = 0.434 m and then sticks to a uniform vertical rod of mass M = 0.688 kg and length d = 2.94 m. The rod pivots about point 0 through angle 6 before momentarily stopping. Find 8. {D Number l Units
