Problem

Two vectors in the plane have components (Ax,Ay)(A_x, A_y) and (Bx,By)(B_x, B_y). Which one of the following gives the yy-component RyR_y of their resultant R⃗=A⃗+B⃗\vec R = \vec A + \vec B? a) Ry=Ay2+By2R_y = \sqrt{A_y^{2}+B_y^{2}} b) Ry=Ay−ByR_y = A_y - B_y c) Ry=Ay+ByR_y = A_y + B_y d) Ry=Ay+By2R_y = \dfrac{A_y+B_y}{2}
