a) If the round must clear a hill 200 meters high at a distance of 2000 meters in front of the howitzer, what c values are permitted in the trajectory equation?
b) If the goal in part (a) is to hit a target on the ground 75 kilometers away, is it possible to do so? If so, for what values of c? If not, what is the maximum distance the round will travel?

You should be able to plug in x, y, g, and v, then solve for c

anonymous · Answer

x=2000, y=200, v=897 and g=9.81

anonymous · Answer

So I use those values where ever I see x, y, v, g in the equation that is given?

anonymous · Answer

Correct. Then you should be able to use algebra and solve for "c". You'll probably get some sort of quadratic which you'll have to interpret the results
