Well first of all, the arrow hits the archer on the way down. Both the truck and the archer have a constant horizontal velocity component of 35 m/s. Your late archer deserved it no doubt
now the vertical problem.
Vi = 98
v = Vi - 9.8 t
0 at top
98 = 9.8 t
t = 10 seconds to top (good archer, strong bow)
so
a) 20 seconds up and down
b) did that, archer dead in truck bed. always turn after dropping a bomb out of your airplane by the way.
c) 20 seconds at 35 m/s = 700 meters
you are, of course, assuming that there was no horizontal component to the arrow's velocity.
In Heinlein's "Stranger in a Strange Land" there is a character who is a professional observer. If you point to a house on a hill and ask what color it is, he'll reply, "This side is white," making no assumptions about the other sides.
However, given the usual sloppy problems posted here, I agree with your analysis (ignoring air resistance).
This dead archer was a dead shot and the duck was directly overhead :) By the way it was an expert seagull pulling out of a bombing run anyway and the archer was simply retaliating.
