[SOLVED] Tractor up a slope The question is as follow... A farm tractor tows a 4300kgs trailer up an incline 26 degrees aboe the horizontal at a steady speed of 3.0m/s. What force does the the tractor exert on the trailer? I've read the section over in which this problem is included in... the section is over find the accerlation and force of in 2 dimensions. well if i'm not mistaken...the accerlation of this problem is 0. F=ma F=4300(0)=0? Doesn't make sense OR if the tractor is pulling this tailer...the tractor is obviously exerting the force of the trailer and then some if it's moving it by 3m/s Am I going in the rigth direction?
