On a straight stretch track a toy car is set rolling with an initial position of 16.0 cm, an initial velocity of-3.1 cm/s, and a constant acceleration of 2.10 cm/s2. at the same moment, another toy car is set rollingon an adjacent track with an initial position of 11.5 cm, an initial velocity of 5.40 cm/s, and a constantzero acceleration. a.at what time, if any, do the two cars have equal speeds? b. what are their speeds at that time? c. at what time(s), if any, do the cars pass each other? d. what are their locations at that time?

Where are the options ?

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.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
