Study the scenario.
A wagon is moving while two horizontal forces are acting on it: 25 N to the right, and 5 N to the left.
Use the vector addition rule to compute the net force acting on the wagon.
20 N to the right
100 N to the right
5 N to the left
30 N to the left
can someone show me how to solve this?
25 - 5 = 20
He just solved it for you. You are moving 25 N to the right, and then you need to move 5 N to the left. Since you just moved 25 N to the right, you go 5 N to the left which means you take away from the 25 since you just moved in the opposite direction.
25 - 5 = 20. So your answer is A, or 20 N to the right.
Did you bother to read what PsyDAG posted above?
To solve this problem, you need to use the vector addition rule to find the net force acting on the wagon. The vector addition rule states that when forces act in the same direction, you simply add their magnitudes, and when forces act in opposite directions, you subtract their magnitudes.
In this scenario, we have two forces acting on the wagon: 25 N to the right and 5 N to the left. Since they are acting in opposite directions, we can subtract their magnitudes.
Step 1: Start by visualizing the forces on a coordinate system. Draw an arrow representing the force of 25 N directed to the right and another arrow representing the force of 5 N directed to the left.
Step 2: To subtract the magnitude of the force of 5 N from the magnitude of the force of 25 N, you subtract 5 from 25. This gives us a net force of 20 N.
Therefore, the correct answer is 20 N to the right.
