Answer :
Final answer:
The kinetic friction between the box and the floor is 50N left, which is equal to the force applied by the student but in the opposite direction.
Explanation:
In this scenario, the kinetic friction can be determined by using Newton's second law of motion. The box is being moved at a constant velocity, meaning that the net force acting on it is zero. Hence, the force exerted by the student to push the box must equal the force of kinetic friction attempting to resist this motion.
As the student is applying a force of 50N, the force of kinetic friction must thus also be 50N, but in the opposite direction (assumed to be left). Therefore, the kinetic friction force between the box and the floor is 50N left.
