physics problem from 16 mini mcats

I'm reviewing my answers from the mini-mcat test 2, does anybody know how they got 3600 m/s for the final velocity? It doesn't even explain this in he back of the book.

well I don't even have the book but knowing the MCAT. I am going to tell you that anything that involves velocity can be solved through the law of conversation of energy which is a lot less time consuming than kinematics and if you are asked for the final velocity. It probably but not always means that all your initial potential energy was converted to kinetic mgh or Force times distance or Fdcos or work =1/2mv squared. Now again remember I don't have the problem but I am pretty sure conservation of energy is sufficient for 90% of the kinematics problems on the MCAT especially when you are dealing with velocity. If this doesn't help then post the question and I'll help you out.

ps
you know you are a true king of all gunners when you find yourself gunning on SDN lol.
