Answer 3

i in this case is the axis. The projection of the vector onto i is the amount of that vector that moves in that direction because it is the dot product of the vector with the unit vector you get

\[vcos\theta\= projection of v on i\]
so find the angle between the vector and the x axis and then plug into that formula. You could also take the dot product of v and i
