Question

Suppose 15 children who weigh the same are playing a game of tug-of-war. Five children pull with 5 newtons of force, while ten children pull with 10 newtons of force in the opposite direction. How can one determine the net force on the rope?

a
The forces are in opposite directions, so the newtons can be divided.
b
The newtons are in the same direction, so the newtons can be multiplied.
c
The forces are in the same direction, so the newtons can be added.
d
The forces are in opposite directions, so the newtons can be subtracted.

Answer 1
