A 6.60 g bullet moving at 603 m/s strikes a 660 g wooden block at rest on a frictionless surface



A 6.60 g bullet moving at 603 m/s strikes a 660 g wooden block at rest on a frictionless surface. The bullet emerges, traveling in the same direction with its speed reduced to 457 m/s. (a) What is the resulting speed of the block? (b) What is the speed of the bullet-block center of mass?
