A 2.4kg box is sliding to the right on a frictionless surface at 3m/s. A 0.75N force horizontal force is applied in the direction of the box's motion over a distance of 1.3m. After traveling the 1.3m, the horizontal force is removed and the box then encounters a long rough patch. The box slides 2.6m over the rough patch before it comes to a stop A. What is the work done by the horizontal applied force? B. What is the speed of the box after it has traveled the 1.3m? C. What is the magnitude of the friction force between the box and the rough patch
