Two men pull horizontally on a box resting on a frictionless surface with ropes attached to the same point on the box. Man A pulls with 23.5 N of force at 34.0o N of W. Man B pulls with 45.0 N of force at 58.0o S of W. Use the space below to draw and label a reasonable diagram, showing compass directions, to illustrate the forces as they are actually applied to the box (as seen from above the box).
