To maintain a constant speed, the force provided by a car's

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/m-. (a) What are the drag forces in newtons at 75 km/h and 104 km/h for a Toyota Camry? (Drag area = 0.70 m- and drag coefficient = 0.28.) at 75 km/h N at 104 km/h N (b) What are the drag forces in newtons at 75 km/h and at 104 km/h for a Hummer H2? (Drag area = 2.44 m and drag coefficient = 0.57.) at 75 km/h at 104 km/h N
