2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how
many...

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...
