An object has a force of 10 newtons from the right and 17 newtons from the left. Once the object starts moving toward the right, an additional force of 7 newtons is applied from the right. What can you conclude about the direction of motion of the object after the application of the additional force?
Before the 7-Newton force is applied:
Fn = 17 - 10 = 7 N. = Net force to the right.
After the 7-Newton force is applied:
Fn = 17-10-7 = 17 - 17 = 0. = Net force.
Conclusion: Since the net force is now 0, the object stops.
To answer this question, we need to analyze the net force acting on the object. The net force is the vector sum of all the forces acting on the object.
In this case, the object has a force of 10 newtons from the right and 17 newtons from the left. Since these forces have opposite directions, we subtract the smaller force from the larger force to find the net force:
Net force = 17 N - 10 N = 7 N to the left
Now, an additional force of 7 newtons is applied from the right. We need to add this force to the net force we already calculated:
Net force = 7 N to the left + 7 N to the right = 0 N
The resulting net force is 0 N, which means there is no unbalanced force acting on the object. According to Newton's first law of motion (also known as the law of inertia), an object at rest or in motion will continue in that state unless acted upon by an external force. In this case, after the additional force of 7 newtons is applied from the right, the net force becomes zero. Therefore, we can conclude that the direction of motion of the object will remain unchanged.
To determine the direction of motion of the object after the application of the additional force, we need to compare the net force acting on the object.
The net force is found by subtracting the forces acting in the opposite direction. In this case, we have a force of 10 N from the right and 17 N from the left.
Net force = Force from the right - Force from the left
= 10 N - 17 N
= -7 N
Since the net force is -7 N, it indicates that the object still has a net force acting in the left direction.
Therefore, based on the given information, we can conclude that the object will continue to move in the left direction after the application of the additional force.
