determine the net force in the following scenario: Mr. Martinez needed to push a lab table across the floor. He pushed with a force of 20 newtons east, but could not move it. He then asked Ms. Carr for help. She pulled with a force of 10 newtons east. Together, they were able to move the table. What was the net force applied to the table?
