Which of the following statements would be an example of a BALANCED force?

• A soccer ball rolls across the grass after being kicked.

• A baseball flies through the air.

• A cell phone falls out of your hand.

• A book sits on a table without moving.

You and your brother are using team work to move a heavy TV.

You are pushing on the TV with 60 N of force and your brother is exerting 70 N of force with you on the same side. What is the net force and which statement would be true about the TV?

• 10 N; The tv would be pulled towards you and your brother.

• 130 N; The tv will be pushed away from you and your brother.

• 0 N; The tv will not move.
