A 4.60 gram bullet moving at 906 m/s strikes a 540 gram wooden block at rest on a frictionless surface. The bullet emerges, traveling in the similar direction with its speed reduced to 413 m/s.
(a) Determine what is the resulting speed of the block?
(b) Evaluate what is the speed of the bullet-block center of mass?
