A Toyota Prius has the following attributes: Drag Coefficient Cd = 0.24, Frontal Area Af = 25.83 ft?, weight = 3064 lb, and Speed = 90 mph. Use air density p = 0.002378 slugs/ft3. If this car is driven up a 2% grade under a head wind speed of 10 mph compute the power required to overcome (a) Aerodynamic Resistance, (b) Rolling Resistance, and (c) Grade Resistance.

Step 1

The given data regarding a Toyota Prius is as follows:

Step 2

(a) Power required to overcome aerodynamic resistance is given below:

Step 3

Aerodynamic resistance force e...
