Suppose you're riding your bicycle in the mountains. You climb a mountain pass on a scenic roadway and prepare to descend the other side of the mountains. You have a choice of two roads you can use to descend. One road is two miles long, while the other is ten miles long. Assuming you apply the same, consistent braking force throughout the duration of your descent for either route, which descent route will allow you to reach the base of the pass with the highest speed? Two-mile (shorter) route Ten-mile (longer) route No difference

7. During impact, particles collide with a very short interaction period. The interparticle impulse during an impact collision includes a deformation impulse as particles undergo some combination of elastic and plastic deformation plus a restitution impulse during which some portion of of the deformation is reversed. The magnitude of the restitution impulse is always greater than that of the deformation impulse. True False

Global Consumption (2016) CO2 350 kg/MWh 260 kg/MWh 200 kg/MWh Type of Fuel Coal 44 billion MWh Oil 51 billion MWh Natural Gas 37 billion MWh Table 1: Global fossil fuel consumption, 2016 4. Globally, fossil fuel energy use was about 132 billion megawatt-hours (MWh) in 2016. Table 1 shows the individual estimates for coal, oil, and natural gas, as well as the carbon intensity of each fuel, given in kilograms of CO2 per MWh of energy consumed. For example, each MWh of coal that is burned releases about 350 kg of CO2. Use the table to estimate the total amount of CO2 (in kilograms, kg) that was emitted in 2016 from the burning of fossil fuels. Start by estimating the amount emitted for each fuel type. Then find the total. You may find it beneficial to use scientific notation. For example 44 billion MWh is 44 × 10° MWh (or 44E9, as entered into your calculator). Round to two significant digits in your final answer.
