Question

Two people are playing tug of war. One person pulls to the right with 32 N (Newtons) of force. The other person pulls to the left with 37 N of force. How strong is the net force and in which direction?

Answer 1

Answer:

5 units to the left.

Step-by-step explanation:

They are working against each other. That means you subtract.

32 - 37 = -5

You are moving 5 units to the left because 37 is negative which means it is moving left. The key word is left. In physics, you would get the same answer if you did it this way.

37  - 32 = 5

The 5 moves in the same direction as the 37

Answer 2

The net force is -5N. Since the net force is negative, hence the direction of the net force is towards the left.

In finding the resultant of the force, we must know that:

• The direction of force towards the right is positive

• The direction of force towards the left is negative

From the question, we are given;

Force towards the right  = + 32N

Force towards the left = -37N

Net force = sum of the forces

Net force = + 32 - 37

Net force = -5N

Since the net force is negative, hence the direction of the net force is towards the left.
