To maintain a constant speed, the force provided by a car's engine must equal the drag force plus the foer offrl iont of the road (the rolling resistance). The density of air is 1.2 kg/m . (a) What are the drag forces in newtons at 79 km/h and 103 km/h for a Toyota Camry? (Drag area drag/' Coefficient z' 0128.) at 79 km/h at 103 km/h (b) What are the drag forces in newtons at 79 km/h and at 103 km/h for a Hummer H2? (Drag are, 4.44 at 79 km/h at 103 km/h Supporting Materials drag coefficient = 0.57.)
