Respuesta :

The net force is 500N downwards.

When Haley is trying to pull an object upward. The below forces are acting on the object. 

Fp = 5500N

Fg = 6000N

because the force of gravity is more than the force of the pull.

Fnet = Fg - Fp = 6000N - 5500N = 500N

And, the direction of the resultant force is the direction of the larger force.

the net force is 500N downwards
