Net Force

Students are playing tug-of-war. If group B pulls the rope to the right with a force of 400 N and group A pulls the rope to the left with a force of 250 N, what will happen to the ribbon in the middle of the rope?

• The ribbon will move to the left and group A will win the tug-of-war.

• The ribbon will move to the right and group B will win the tug-of-war.

What is the net force?

• 65 N left

• 65 N right

• 35 N left

• 35 N right

Two teams were having a tug of war.  Team A had four people on the team, and the whole team pulled with 25N of force.  Team B had three people on the team, and the whole team pulled with 35 N of force.  Which team won, and how much greater was their net force on the rope?

• Team B by 10 N

• Team B by 30 N

• Team A by 20 N

• Team A by 65 N
