A steam train moving with a speed of v=60kmh β1 is brought to rest by first shutting off the steam, when the train runs against a resistance equal to 1/100 of its weight, and later by applying the brakes, at which point the train runs against a force 1/8 of the weight of the train.
If the steam is shut off when the train is a distance d=0.33km from a station, find the distance from the station that the brakes must be applied in order that the train may be brought to rest in the station.

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 of a column of water 1.00 km high for a temperature increase of 1.00ΒΊc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in Γ10^{-3} β3 m)
