I am finding myself stuck on what is likely considered a very basic problem. I know the answer (it's in the book) but after 20 minutes of searching and trying to find a method, I've turned to you. Could someone please describe the methodology for this? A farm tractor tows a 4300kg trailer up a 26-deg incline at a steady speed of 3.0m/s. What force does the tractor exert on the trailer? (ignore friction). *This is a section in the book before Normal and frictional forces, so I assume they are not incorporated *If the velocity is constant, isn't the acceleration then zero, thus making F zero? *Is there some equation that I am missing that links mass, Fx=Fcos26, Fy=Fsin26, and speed?
