Unit 4 Physics Review

Betty Sue pulls on a box with a force of 18 N to the right. Robert pulls the same box from the opposite side with a force of 20 N to the left. What will be the result?

• The box will move up because of the combined force of 38 N.

• The box will move to the left because of a net force of 2 N.

• The box will move to the right because of a net force of 2 N.

• The box will remain at rest.
