Hello,
I hope it is ok to post a physics problem here.
Q: A 1,280-kg car pulls a 350-kg trailer. The car exerts a horizontal force of 3,600-N against the ground in order to accelerate. What force does the car exert on the trailer? Assume an effective friction coefficient of 0.15 for the trailer.
Normal force on trailer is 9.8*350=3,430-N. So the force of Friction is -0.15*3430= -514.5-N.
I am stuck here without knowing either the magnitude of the acceleration or the coefficient of friction for the car.
Any guidance as to what I am missing will be greatly appreciated.
Thank you
