Final answer:
The net force applied is 250N. The players will move in the direction of the stronger force.
Step-by-step explanation:
The net force applied can be found by adding the two forces together. In this case, the defensive line is applying 100N of force and the offensive line is applying 150N of force. Therefore, the net force applied is 100N + 150N = 250N.
The direction of the two players will depend on the relative magnitudes and directions of the two forces. If the defensive line is stronger and pushing with more force, the two players will move in the direction that the defensive line is pushing, which would be towards the offensive line. On the other hand, if the offensive line is stronger and pushing with more force, the two players will move in the direction that the offensive line is pushing, which would be away from the defensive line.
