Two cars are traveling on a desert road. after 5.0 seconds they are side by side at the next telephone pole. the distance between the poles is 112m.
identify the following quantities:
a. the displacement of car a after 5.0s
b. the displacement of car b after 5.0s
c. the average velocity of car a during 5.0s
d. the average velocity of car b during 5.0s

The question looks incomplete, but according to the information given above seem like they have identical journeys.
a. the displacement of car A -  65.5 m 
b. the displacement of car B  - 65.5 m
c. average velociry of A  
d. the average velocity of car B  has the same. 

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.
