Correction to Chapter 2 Test Review

Question 16 does not give enough information to solve.  It should read like this:

At a 4th of July fireworks display, a man stands 40 feet away from a bottle rocket being shot vertically into the air at a rate of 25 feet per second.  At what rate is the angle of elevation between the man and the bottle rocket changing when the bottle rocket is 40 feet in the air?

Please also note that I have changed the height of the bottle rocket from 30 feet to 40 feet.  This will make calculations easier.  Hope this helps.
