What is the resulting speed of the block

Reference no: EM13336948

A 5.50 g bullet moving at 688 m/s strikes a 860 g wooden block at rest on a frictionless surface. The bullet emerges, traveling in the same direction with its speed reduced to 469 m/s.

(a) What is the resulting speed of the block?

(b) What is the speed of the bullet-block center of mass?
