When the Tesla S is plugged in at home, it is connected to a 220 volt (V) 50 Amp (I) charger.
a) Given this equation P = V x I (Power = Volt x Amp), what is the electric power (in kW)
delivered to the Tesla Battery once plugged in?
b) Accounting for a 10% efficiency loss (heat, cable resistance, battery efficiency), How many hours are needed for a full charge?
**In a previous problem it was mentioned that Tesla S is equipped with a 60 kWh battery on board. This vehicle uses on average 300 Wh per mile driven.

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...
