A steel ball is at one end of a box that is moving forward as shown. The box suddenly stops. According to Newton's first law, what happens to the steel ball just after the box stops?

• Because of friction, the ball continues rolling forward at the same speed.

• Because of friction, the ball rolls forward at an increased speed.

• Because of inertia, the ball continues rolling forward at the same speed.

• Because of inertia, the ball rolls forward at an increased speed.

Which statement best describes an action-reaction force pair in this situation?

• The wall pushes on the skater when the skater pushes on the wall.

• The wheels slow down, and the skater stops

• The skater exerts a force on the wall, and the wheels exert a force on the floor and begin to turn.

• The friction of the floor decreases when the wheels roll on the floor.
