As lucy pushes a box across the floor, she exerts a force on the box in the forward direction. what is the equal and opposite force in this interaction, according to newton\'s third law?

the right answer is 0.3 meters per second

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
