How many times larger is the elephant's momentum than the momentum of a 0.033-kg tranquilizer dart fired at a speed of 350 m/s?

Elephants Momentum Sp= EM Sp=(5400 kg (Average weight of an Asian Elephant))(4.5 m/s ( Average walking speed) ) = 24300 kg m/s Momentum of Dart: D=MD MD=(0.033 kg)(350 m/s) = 11.55 kg m/s Elephant has more momentum

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.
