I am stuck on a question that asks for the resultant force(magnitude + direction)
question says :
A rope is strung between a car and Joe, the car pulls on the rope with a force of 20,000 newton. joe pulls the rope with a force of 25,000N. what is the resulatant force?
dont u find the resultant force by adding them togather if the same, if not subtract force A- Force B wel.. then it would be 20,000-25,000 which is negative= -5,000 does that make since? or should it be 25,000-20,000?
You add the forces, but since the force is in opposite directions, they will have different signs. So the result is that you effectively subtract them. The net force will be in the direction of the larger force.
The resulting sign of adding two forces just indicates the direction of the net force.
two force of 20N and 34N act on a body in such a way that they make an angle of 35 with each other. find the resultant of the two force
To find the resultant force (magnitude + direction) in this scenario, you need to apply vector addition. Here's how you can do it:
Step 1: Define the positive direction: In this case, let's assume that the direction in which Joe is pulling is positive.
Step 2: Assign positive and negative signs to the forces: The car pulling on the rope with a force of 20,000 N should be assigned a negative sign because it is pulling in the opposite direction of Joe. Joe pulling on the rope with a force of 25,000 N should be assigned a positive sign because it is pulling in the same direction.
Step 3: Add the forces together: Since we have assigned the appropriate signs, we can add the forces together to find the resultant force. In this case, it would be: 25,000 N - 20,000 N = 5,000 N.
Step 4: Determine the direction: The resultant force is positive, indicating that the direction is the same as the direction Joe is pulling. Thus, the resultant force is 5,000 N in the direction in which Joe is pulling.
Therefore, the resultant force is 5,000 N in the positive direction (the same direction as Joe's pull).
