Suppose 25 children who weigh the same are
playing a game of tug-of-war. Five children pull
with 10 newtons of force, while ten children pull
with 15 newtons of force in the opposite direction.
How can one determine the net force on the rope?
(1 point)
The forces are in opposite directions, so the
newtons can be subtracted.
The forces are in the same direction, so the
newtons can be added.
The newtons are in the same direction, so the
newtons can be multiplied.
The forces are in opposite directions, so the
newtons can be divided.
The forces are in opposite directions, so the newtons can be subtracted.
To determine the net force on the rope, you need to consider the direction and magnitude of the forces involved. In this case, five children are pulling with 10 newtons of force in one direction, and ten children are pulling with 15 newtons of force in the opposite direction.
Since the forces are in opposite directions, you subtract the forces to find the net force. To do this, you can add up the magnitudes of the forces and assign appropriate signs (+ or -) to indicate the direction.
In this scenario, the net force can be calculated as follows:
Net force = (10 N × 5) - (15 N × 10)
= 50 N - 150 N
= -100 N
Therefore, the correct answer is: The forces are in opposite directions, so the newtons can be subtracted.
