Hi there, I have a question that I'm not sure to go about solving:
A car of mass 700kg is towing a trailer of mass 500kg, on an incline of 30 degrees to the horizontal.
Friction on the trailer is 400N, friction on the car is 600N. If the engine provides a driving force of 700N, what is the tension in the towbar?
I guess I need to first work out the acceleration of the system, but I think a bit unclear as to what driving force is...
In this case wouldn't the car and trailer no be moving, as the driving force is less than the combined friction on the system?
Thanks for your help.
