A man sits in a cannon and lights the fuse. A force of 6000N propels him out of the barrel (which is 2.5 meters long) in a time of .35 seconds. The man has a mass of 85 kg.

1. How much work is done on the man by the cannon? (ignore man's weight)
2. What is the average power exerted on the man?
3. How high above the cannon does he rise during his flight?
