Acar is traveling on a straight, level road under wintry conditions. seeing a patch of ice ahead of her, the driver of the car slams on her brakes and skids on dry pavement for 50 m , decelerating at 7.5 m/s2 . then she hits the icy patch and skids another 70 m before coming to rest.
a) if her initial speed was 78 mi/h , what was the magnitude of the deceleration on the ice?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
