Two children are pulling a rope from opposite ends. The child on the left pulls the rope with a force of 100 N and the child on the right pulls it with a force of 55 N. What is the net force acting on the rope and in which direction is it acting?
Solution:
The child on the left is pulling with a force of 100N
The child on the right is pulling with a force of 55N
The net force would be the difference between 100N and 55N. 100N-55N= 45N
The stronger force is pulling to the left
The answer is that the rope will move to the left with a force of 45N.
