(Questions 16-18) A 25 kg box is at the bottom of a frictionless incline that is 7 m long as shown and makes an angle of 20 degrees with the horizontal. A person applies a constant horizontal (NOT parallel to the incline, but horizontal) force to the box, starting from rest. It reaches the top of the ramp in 13 seconds. 16. Draw a free-body diagram of this situation showing all forces on the box. 17. What was the magnitude of the box's acceleration during this process? 18. What was the magnitude of the force applied by the person?
