Using the air drag force formula from the lab manual, estimate the maximum speed vmaxvmax of a 2004 Toyota Prius. The height of the car is 1.48 m and the width is 1.72 m. Use these two values to get the size of the cross-sectional area AA of the car. The value of the drag coefficient for the Toyota Prius is given as CDCD = 0.26 (dimensionless). The density of air at 20Ā° C is equal to rhorho = 1.20 kg/m3. The maximum pulling force of the Prius' 76 hp combustion engine at the top gear is equal to 1085 N. Calculate the maximum (also called terminal) speed of this car. Remember that at the terminal speed, air resistance force is equal and opposite to the pulling force, so the car cannot accelerate anymore.
