Various forces act on the cars with magnitudes and directions. All forces act in the horizontal plane and are either parallel or at 45 or 90 degrees to the car's motion. Rank these cars on the basis of their speed a short time after the forces are applied. Rank from largest to smallest. To rank items as equivalent, put an equal signs between them. ?
