Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 700 kg. the satellite is initially at position < 3.3, -1.6, 2.0> m and has a speed of 6 m/s. you exert a force < -400, 500, 250> n. when the satellite reaches the position < 2.3, 2.6, -11.8> m, its speed is 6.18 m/s. how much work did your friend do?

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.
