A 1100-kg car is coasting on a horizontal road with a speed of 19 m/s. After passing over an unpaved, sandy stretch 32 m long, the car's speed has decreased
to 12 m/s. What work was done on the car to change its kinetic energy?

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 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
