Haley is trying to pull an object upward. The below forces are acting on the object. Fp = 5500N Fg = 6000N Which represents the net force? ← 500N → 500N ↑ 500N ↓ 500N

For this case, the first thing we must do is define a reference system.

Suppose that the positive direction of the reference system is upward.

We have that the sum of forces in the vertical axis is given by:

Fy = Fp - Fg

Substituting values:

Fy = 5500 - 6000

Fy = - 500

The negative sign means that the direction of the force with respect to the defined coordinate system is downward.

Answer:

The net force is:

↓ 500N
