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?
To determine the net force on the rope, we need to find the vector sum of all the forces acting on it.
In this scenario, there are two groups of children pulling with different forces in opposite directions. The first group, consisting of five children, pulls with a force of 10 newtons. The second group, consisting of ten children, pulls with a force of 15 newtons in the opposite direction.
Since all the children in each group weigh the same, we can assume that each child in the first group contributes a force of 2 newtons (10 newtons divided by five children), while each child in the second group contributes a force of 1.5 newtons (15 newtons divided by ten children).
To find the net force, we sum up the forces in each direction.
For the first group, which is pulling towards the positive direction, the total force is:
5 children × 2 newtons/child = 10 newtons.
For the second group, which is pulling towards the negative direction, the total force is:
10 children × 1.5 newtons/child = 15 newtons.
To find the net force, we subtract the force in the opposite direction from the force in the positive direction:
Net force = 10 newtons - 15 newtons = -5 newtons.
Therefore, the net force on the rope is -5 newtons, indicating that the overall force direction is towards the negative side.
To determine the net force on the rope, we need to consider the forces applied in each direction.
1. Calculate the total force exerted by the five children pulling with 10 newtons of force:
Total force = 5 children × 10 newtons/child = 50 newtons
2. Calculate the total force exerted by the ten children pulling with 15 newtons of force in the opposite direction:
Total force = 10 children × 15 newtons/child = 150 newtons
3. Since the forces are acting in opposite directions, we need to subtract the smaller force from the larger force to find the net force:
Net force = 150 newtons - 50 newtons = 100 newtons
Therefore, the net force on the rope is 100 newtons.
To determine the net force on the rope, we need to consider the individual forces acting in opposite directions and find their vector sum. In this scenario, there are two groups of children pulling with different forces.
First, let's calculate the total force exerted by the group of five children pulling with 10 newtons of force. Since there are five children, each exerting 10 newtons of force, we multiply the force by the number of children: 5 children * 10 newtons = 50 newtons.
Now, let's calculate the total force exerted by the group of ten children pulling with 15 newtons of force. Following the same process, we multiply the force by the number of children: 10 children * 15 newtons = 150 newtons.
Since the forces are in opposite directions, we need to consider their signs. Let's assume that the force exerted by the first group is positive (as they pull to the right), and the force exerted by the second group is negative (as they pull to the left).
Finally, to find the net force, we add the two forces together: 50 newtons + (-150 newtons) = -100 newtons.
Therefore, the net force on the rope is -100 newtons, indicating that the direction of the force is towards the left.
