Fox's Master was out here on my behalf. After reading through the thread and digesting all the math, I came up with this:
Intercept Calculator
Let me know what you think.
Thanks
I did some spreadsheets like this years ago, I'll see if I can find them. The spreadsheet seems to be making some different assumptions than the origial problem. In the spreadsheet the target is travelling at constant velocity before the interceptor leaves and in the problem it is accelerating. This will change the target displacement figure.
I see you also added vectors and Trig to your sheet. In the original problem they both left the same point along the same tragectory.
But this gives me something to do in a saturday Morning. I'm gonna play around with this.
