## Fundamentals of Physics Extended (10th Edition)

E={$F_{2}$,$F_{4}$} F={$F_{2}$,$F_{4}$} G and H are impossible.
Kinetic energy is a scalar quantity, so it can never be negative and the direction of travel is irrelevant when calculating kinetic energy. $F_{2}$ and $F_{4}$ are equal to each other and greater than the other two forces, so they are plot E with greater kinetic energy. $F_{2}$ and $F_{4}$ are equal and less than the other two so they are plot F.
