A 750.0 N man, carrying a 2.0 kg physics textbook, stands at the center of a frozen pond of radius 10.0 m. He is unable to get to the other side since there is no friction at all between his shoes and the ice. To overcome his difficulty, he throws his textbook horizontally at a speed of 6.0 m/s toward the north shore. How long (in s) does it take him to reach the south shore

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.
