4. An object is rolled off the side of a cliff with a horizontal velocity of 26.7 m/s. The object lands 103.3m from the base of
the cliff. How tall is the cliff? (*HINT* You must calculate for time
first, then solve for the height)

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
