Aman holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.480 m/s. the total mass of the sled, man, and rock is 96.0 kg. the mass of the rock is 0.310 kg and the man can throw it with a speed of 14.5 m/s. both speeds are relative to the ground. determine the speed of the sled if the man throws the rock forward (i. e. in the direction the sled is moving).
also determine the speed of the sled if he throws the rock directly backwards.

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)
