Anna got fed up and decided to put some of her classmates in a big box. She shoved Riley, Justin, and Paul into the box and taped it shut. Anna couldn’t overcome the force of friction by herself, so she asked some classmates to help push the box out the door. The force of friction of the floor on the box was 400 N.
