Question
Two construction workers are attempting to pull a slab of concrete off of the ground. Each of the workers are pulling up with a force of 225 N, while the slab of concrete applies a gravitational force of 400 N in the opposite direction, remaining stationary.
If the pulling forces applied to the slab of concrete are assigned a positive value, what is the net force of the scenario, and in which direction will the slab of concrete move?

Responses
-175 N; the slab will remain stationary
-175 N; the slab will remain stationary
-50 N; the slab will remain stationary
-50 N; the slab will remain stationary
175 N; the slab will move upward
175 N; the slab will move upward
50 N; the slab will move upward
