A0.156 kg ice puck collides with a 0.170 kg ice puck. both were originally moving at the same speed. which one has the larger change in velocity? they both have the same change in velocity. the 0.156 kg puck changes velocity the most. they both have no change in velocity. the 0.170 kg puck changes velocity the most.

When the two pucks collide, momentum will still be same but it acts in two different directions. Momentum formula goes like this M = m x v, m is mass and v is speed. That means velocity is inversely proportional to mass. So the puck with less weight changes the most, so the 0.156 kg puck changes velocity the most .

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.
