At a certain part of yourdrive from home to school, your car (mass = 1400 kg) will coast inneutral at a constant speed of 84 km/h if there is no wind. Examination of a topographical map shows that for this stretch ofstraight highway the elevation decreases 200 m for each 6000 m ofroad. What is the total resistive force (friction plus airresistance) that acts on your car when it is traveling at 84km/h?
