The Problem:(adsbygoogle = window.adsbygoogle || []).push({});

Your car breaks down in the middle of nowhere. A tow truck weighing 4000 lbs. comes along and agrees to tow your car, which weighs 2000 lbs., to the nearest town. The driver of the truck attaches his cable to your car at an angle of 20 degrees to horizontal. He tells you that his cable has a strength of 500 lbs. He plans to take 10 secs to tow your car at a constant acceleration from rest in a straight line along a flat road until he reaches the maximum speed of 45 m.p.h. Can the driver carry out the plan? You assume that the rolling friction behaves like kinetic friction, and the coefficient of the rolling friction between your tires and the road is 0.10.

I'm not sure where to start. I'm pretty sure I need to find the sum of all the forces in the x direction, then use the angle of 20 degrees to see if the the tension on the rope is more that 500 lbs. Mainly, im just not sure how to incorporate the kinetic friction. If anyone could provide a hint as to how incorporate the kinetic friction, or just let me know if I'm even on the right track, I'd appreciate it. Thanks
