Chapter 4, Problem 4P

4 * The x- and y-components of several unknown forces are listed below $\left(F_x,F_y\right)$. For each force, draw on an x, y coordinate system the components of the force vectors. Determine the magnitude and direction of each force: (a) $\left(+100\text{N,}\text{-100N}\right)$, (b) $\left(-300\text{N,}\text{-400N}\right)$, and (c) $\left(-400\text{N,}\text{+300N}\right)$.
