To determine which object will reach the bottom of the ramp first, we will need to know their speeds at the bottom of the ramp. The object which moves faster when reaching the bottom of the ramp will also be the one who gets there first. Use the equation that we found in the preceding question to solve for the speed (v).

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)
