To maintain a constant speed, the force provided by a car's engine must equal the drag force plus the
force of friction of the road (the rolling resistance). The density of air is 1.2 kg/m3.
(a) What are the drag forces at 76 km/h and 109 km/h for a Toyota Camry?
(Drag area = 0.70 m2 and drag coefficient = 0.28.) at 76 km/h N at 109 km/h N
