Tractor on an incline

  1. Nov 23, 2008 #1
    The problem states that a 3900kg trailer is pulled by a tractor up a 16 degree incline with a steady speed of 3.0m\s.

    I am asked what force the tractor exerts on the trailer.

    I said that the force was equal to the (W)(sin)16degrees, i get the right answer in the back of the book but i think its a coincidence....any help on this one would be much appreciated

    me again! Your answer is right. Because you're not accelerating the trailer up the incline, there is no additional force required. All you need to do to maintain the speed of 3ms-1 is to overcome the backward force down the slope.
