9. A 37.0 kg box is being pushed by a person across a horizontal floor with a force F = 135 N that makes an angle 0 = 29.0 with the horizontal as shown in the figure. What is the magnitude of the acceleration of the box if the coefficient of kinetic friction between the box and the floor is 0.21? m/$2 10. According to Newton's third law, what is the reaction force in the previous question to the normal force of the floor on the person? O The normal force of the floor on the box O The weight of the box O The gravitational pull of the box on Earth The weight of the person O The force of the box on the person The normal force of the box on the floor O The normal force of the person on the floor The force of the person on the box The gravitational pull of the person on Earth
