An aircraft weighing 21,430 N returns to the aircraft carrier and lands. It goes from 385.3 kilometers per hour (kph) to 0 kph in 2.5 seconds. What is the force required to bring the aircraft to a safe halt? (in N)? CAUTION: Think about what is happening in a physical sense and that it matches your answer.

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
