A boat has a cannon on board that faces aft. The boat is capable of traveling at 15 m/s on still water. The boat is traveling North on a river that has a current flowing south at a rate of 10 m/s. Following 20m directly behind the boat is a raft that is traveling at 13m/s relative to the water. On the raft is a clown with a hoop. The cannon fires the cannonball at 38.5โ with velocity 20m/s. At what velocity must the clown throw the hoop in order for the cannonball to travel through it? Assume the clown throws the hoop straight up.

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 1.00ยบc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ร10^{-3} โ3 m)
