Answer:
60N
Step-by-step explanation:
The net force on the cabinet is 60N.
Net force is that single force that will act like all other forces on a body. The direction of the force and magnitude is very important when resolving forces.
Force applied by Mrs. Moran = 30N
Force applied by Mr. Moran = 30N
Since they each stood on both sides and pushed, the net force will be 30N + 30N = 60N
