Problem 23PE

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). (a) What are the magnitudes of drag forces at 70 km/h and 100 km/h for a Toyota Camry? (Drag area is 0.70 m? ) (b) What is the magnitude of drag force at 70 km/h and 100 km/h for a Hummer H2? (Drag area is 2.44 m2 ) Assume all values are accurate to three significant digits.

Step-by-Step Solution:

Step-by-step solution Step 1 of 5 The car engine provides the force that balances the drag force and the force of friction on the road. The drag force is, Here, is the density of the fluid’s edium, is the drag coeffici ent and A is the area of the object that faces the fluid. Step 2 of 5 (a) The drag force on the Toyota car at speed is, The speed of the car The area of drag The density of the air The drag coefficient The air drug Step 3 of 5 The drag force on the car at speed is, The speed of the car The area of drag The density of the air The drag coefficient The air drug Hence the drag force on the Toyota Camry with speed is and the drag force on the Toyota Camry with speed is .
