The resultant is a parabola
y = 1/2*4t^2
x = 3t
y= 2 (1/3x)^2
y=2/9x^2
Ho, ho, ho.

The resultant would be sqrt(3^2 + 4^2) = sqrt(25) = 5
But there is a problem with the figure. You are to add 2 vectors, except that the horizontal vector is a momentum vector and the vertical vector is a force vector. Foce and momentum are of different units and dimensions, so it's just physically meaningless to add them up.

A + B = R
4^2 + 3^2 = R^2
squrt(25) = squrt(R^2)
5 = R
(Don't 4get the negative signs if any vector is classified as negative)

4^2 + 3^2 = C^2
C=5, Resultant =5

Is this a puzzle you know the answer to, and just want to see who else knows?
Well, I don't "know" but since the two vectors are not really compatible, I'd say the magnitude of the resultant is zero, certainly the dot product is zero for two perpendicular vectors.
