Upgraded fuel economy stnadards released in 2010 call for a 34.1 mile-per-gallon a verage for new cars adn light trucks in 2016. A politician opposing this increase claims it will save "only a drop in the bucket" compared with the 2010 fleet average of about 23 MPG. Formulate a counterargument showing the increase- once the entire fleet reaches 34.1 MPG- could signifigantly reduce the US gasoline consumption rate from its 2010 value of about 380 million gallons per day. State any additional assumptions you make.

Solve the following problem. Round off the final answer to three decimal places. A popular web site state that a 200 pound person will burn 450 calories/hour bicycling (moderate effort) and 650 calories/hour rock climbing (ascending). A 150 pound person decides to start a training routine in which she will bicycle for 45 minutes, 3 times a week and rock climb for 1.50 hours every weekend. How many calories will she have burned after 8 weeks of training (assuming she consumes at the same rate)?

5. For most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case. Please state the following (apply your problem solving strategy): A. REASON: State and describe the overall physical principles you think apply to solve this problem. 3. ASSESS: What is the energy content in kJ of gasoline in 1 g of fuel?

During a one-year time period, how many gallons of water would the average household save by using an efficiency washer vs a regular washer? Is this one-year savings more or less than the amount of water an average person drinks in a lifetime? Explain and show your assumptions, calculations, and conversions.Consider it to be 2 separate problems:1. How much water is saved in a one-year period when using an efficiency washer vs regular washer - answer based on your assumptions and calculations for full credit2. How much water does an average person drink in a lifetime – arrive at this answer based on your assumptions and calculations3. Compare the answers to those 2 questions to arrive at your conclusionBelow are 2 pieces of information that you might find helpful there are 128 oz in a gallonthere are 365 days in a year and also 52 weeks in a year
