4. Storage batteries (Li ion, solid polymer electrolyte) that have small volumes and masses and high energy storage densities are in demand for both electric and hybrid vehicle applications. Estimate the smallest weight battery that could be used to provide full vehicle power for one hour of urban commuting in a family-sized five-passenger sedan. And, do some research to determine if the range (energy and mass) you calculated is realistic. Explain why or why not in 2-3 sentences. You can assume: The minimum power levels for such vehicles are 20 hp at average speeds, and the maximum power levels are 40 hp at peak acceleration. One hour of driving = 40 hp for 15 minutes + 20 hp for 45 minutes Li ion solid polymer electrolyte batteries have a specific energy density of 1400 kJ/kg

A family wishes to buy a 2020 Toyota Camry. The two options the consider are (a) a standard automobile with and SI engine that gets 34 mpg and costs $18,000; and (b) a hybrid automobile that gets 52 mpg and costs $32,000. On average, the family drives 16,000 miles each year ad gasoline costs $1.65 per gallon. Calculate: (Show your complete solution) The amount of gasoline each vehicle would use each year. Gasoline cost savings of hybrid over standard. Time in months it would take to make up the difference in vehicle cost with fuel savings.

2. (Inspired by a walk in Baker Student Center.) An escalator handles a steady load of 30 people per minute taking them from the first to the second floor through a vertical rise of 24 feet. Let us say the average person riding the elevator weighs 160 lb. a. What output power on a motor do you require to drive the unit? Take literally one minute to find an electric motor online that could do this job. You can search “_ hp electric motor" and state the motor name, power, cost, and vendor. Of course, round up your hp, not down to meet your specs. (In practice, this is an area where you can spec the motor in equivalent Watts, if you choose.) b. What is the electric power that is input to the motor considering losses within the escalator system due to friction, vibration, etc.? Your chosen motors surely have a different efficiencies and sources may even present efficiency as a function of power/rpm, so let's all use the value of e= 0.85 for consistency.
