Student X pushes a 15-N box with a force of 10 N to the left. At the same time, Student Y pushes the same box with a force of 5 N, but in the opposite direction. Which would most likely occur? (Ignore friction.) The horizontal force on the box would be 5 N to the left. The horizontal force on the box would be 0 N, the box would not move. The horizontal force on the box would be 15 N to the left. The horizontal force on the box would be 5 N to the right.
