A bullet of mass \(\rm 8 g\) moving with velocity \(\rm 400 ms^{-1}\) gets embedded in a freely suspended wooden block of mass \(\rm 800 g\). What is the velocity acquired by the block?

I keep getting \(\rm 4 ms^{-1}\) but my course module says it's \(3.96 \rm ms^{-1}\).

momentum conservation
8 X 400 = 808 X (velocity of wooden block)
