The initial speed of the bullet is 822 m/s, and the speed of the bullet after it exits the block is 439 m/s. at what speed does the block move after the bullet passes through it?

Linear momentum is conserved, so the speed of the block after
the bullet has passed through it and continued on its way is

        (383 · mass of the bullet)  divided by  (mass of the block)

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
