a red car and a green car move toward each other in adjacent lanes and parallel to an x axis.
At time t=0, the red car is at x = 0 and the green car is at x = 220 m.
If the red car had a constant velocity of 25.0 km/h, the cars would pass each other at x = 44.8 m. On the other hand, if the red car had a constant velocity of 50.0 km/h, they
wouldpass each other at x = 76.5 m. What is (a) the initial velocity of the the green car? Include the signs.

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.
