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 with a net force of 150N and group A will win the tug-of-war.

• The ribbon will move to the left with a net force of 650N and group B will win the tug-of-war.

• The ribbon will move to the right with a net force of 150N and group B will win the tug-of-war.

• The ribbon will move to the right with a net force of 650 and group A will win the tug-of-war.

A cyclist traveling at 25 km/hr turns sharply to the left. This means the forces involved are_____________________.

• Balanced, because the cyclist's speed did not change.

• Balanced, because he was still moving forward.

• Unbalanced, because the mass of the bicycle remained constant.

• Unbalanced, because his direction changed.
