A Toyota Prius has the following attributes: Drag Coefficient Ca = 0.24, Frontal Area Af = 25.83 ft?, weight = 3064 lb, and Speed = 90 mph. Use air density p = 0.002378 slugs/ft3. The vehicle from problem 2 above is travelling down a 4% grade on pavement located at 5000-ft altitude (p = 0.002045 slugs/ft?) with its maximum speed. Overall resistance for the motion of the car at maximum speed is overcome with a power of 28hp. Determine the...

Problem 2 A 4,000 lb. vehicle (Cp = 0.45, AF = 33 ft?) is being driven on a paved surface at sea level (p = 0.002378 slugs/ft) at a speed of 70 mph. The available tractive force of the vehicle is 400 lb. The vehicle encounters a mountain (yes, the mountain is at sea level) with a very steep grade (G=0.08 ft/ft) that extends for precisely 2 of a mile before leveling out. Assuming the air density remains constant and...

A 2790 lb car has a frontal cross-sectional area A of 21.1 ft2, a drag coefficient Cd of 0.25, and a drive (or tractive) force of 280 lbs. Assume an air density of 2.3x10-3 slug/ft?, Here is a list of frontal areas and drag coefficients for cars. This web site has interesting information on how the physics we are learning is incorporated into video games with cars.

2. The electric vehicle Tesla Model S has a drag coefficient of 0.24, a mass of 2100 kg, and a frontal area of 2.4 m2. The coefficient of rolling resistance of its tires is 0.01. Recall the density of air at sea level is 1.3 kg/m3. How much kinetic energy is required to overcome rolling resistance and air resistance (drag) at Autobahn speeds of 180 km/hr for a 200 km trip? How much useful energy (in MJ) and money (in...
