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 250 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? (1 point) Responses -100 N; the slab will remain stationary -100 N; the slab will remain stationary 50 N; the slab will move upward 50 N; the slab will move upward -150 N; the slab will remain stationary -150 N; the slab will remain stationary 100 N; the slab will move upward
The net force can be calculated by adding up all the forces:
Total force = Force applied by Worker 1 + Force applied by Worker 2 - Force of gravity
Total force = 250 N + 250 N - 400 N
Total force = 500 N - 400 N
Total force = 100 N
Since the net force is 100 N in the upward direction, the slab of concrete will move upward. Therefore, the correct response is:
100 N; the slab will move upward
