A 4.00 g bullet travelling horizontally with a magnitude of 440 m/s is tired into a wooden block with a mass of 0.80 kg intitially st rest on a level surface. The bullet passes through the block and emerges with its speed reduced to 160 m/s. With the info, what physics concept is the one that allows us to determine the speed of the block just after the bullet has passed through the block?
