A $7\mathrm{.}00$ g bullet moving at $\backslash (911\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ strikes a $900$ g wooden block at rest on a frictionless surface. The bullet emerges, traveling in the same direction with its speed reduced to $\backslash (482\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).($a$)$ What is the resulting speed of the block? $($b$)$ What is the speed of the bullet$-$block center of mass?
