Draw a net force arrow on the picture below. What is the net force? State the direction.
2 answers:
Answer:
Net force=0 N
Explanation:
The drawing will look like the attached image, with no net force on the object. We stablished a reference system located in the center of the body, with + axis take right and upward for x and y. All forces are on the x axis, there is one positive force of 7 N (pointing right) and to negative forces of -4 and -3 N (pointing left) if we add the vectors in the x axis we have that
+7-4-3=0 N
The net force is then 0 newton and the drawing has no net force vector then
