Well the force of gravity is (-9.8 )(2 kg) = -19.6 N. FNet must be > 0 to accelerate upwards, so the force upwards must be above 19.6 N.

...scratching head because it now hurts...

I have no idea how much wind you would need though for a 40-sq foot kite in order to give that much force, but it's a considerable amount. (I'll be totally honest and say that I forget the formulas that would let me find that out :P)

Anyway, very neat shots, my insurance would cover it... but I don't dare to try anyway :P

yeah ...um...i thought that was the formula...i just um...couldnt remember all of it too..i mean either.:D
