Question

1. net force: _ n forces are: balanced unbalanced object will: not accelerate accelerate

Explanation:

Step1: Resolve forces into components (assuming x - y axes).

Let's assume the 5N force has components and the 9N force has components. For simplicity, if we consider the two - force case and find the net force using vector addition. We can use the law of cosines for non - perpendicular forces. But if we assume the forces are in opposite directions along a particular line of action (by some geometric arrangement), we subtract the magnitudes of the forces. Here, if we consider the forces acting along a single effective line (after resolving or considering the overall effect), the net force $F_{net}=|9 - 5|=4N$.

Step2: Determine force balance.

Since $F_{net}=4N
eq0$, the forces are unbalanced.

Step3: Predict object's motion.

According to Newton's second law $F = ma$, when there is a non - zero net force ($F_{net}
eq0$), the object will accelerate.

Answer:

Net force: 4N
Forces are: unbalanced
Object will: accelerate
