Show in terms of ao and b. Part 3) determine the plane's a(t). Show in terms of ao and b. Part 4) determine t = T* and s = S* when v reaches a determined takeoff value V*. Show T* and S* in terms of ao, bv and V*

3 Math Practice Name: Physics 357 Some Initial Math Practice, Part 2 Unit analysis is the method by which you use ratios, or fractions, to convert quantities between units, e.g., inches to meters or seconds to minutes. The trick is to establish ratios whereby the unit that you want lives in the numerator and does not get canceled out by the denominator. Here are two examples: How many quarters are in $5? Well, you know there are 4 quarters in a dollar, so.. quarters X 5 dollars 0 quarters 1 dollar 1 Note that the dollars in the numerator cancels out with the dollar in the denominator, so what you're left with is quarters. How many dollars is 17 quarters? 1 dollar 17 quarters 4.25 dollars - X 4 quarters 1 Note that we just flipped the conversion ratio to get the units that we wanted in the numerator! 1. How many miles is 2200 meters? (By the way, don't just google it! - do a web search or look in a physics text to find the conversion ratio and then set it up like the example above) 2.…

Learning Goal: To practice Tactics Box 1.3 Making a unit conversion. One effective method of performing unit conversions begins by noticing that since, for example, 1 mile 1.609 km, the ratio of these two distances-including their units-is equal to one, so that 1 mile 1.609 km 1.600 km 1 mile 1. Such a ratio of values that is equal to one is called a conversion factor. The tactics described here show how to make a unit conversion using conversion factors. Part B Use the fact that 1 inch = 2.54 cm and convert 39 inches into the equivalent length in centimeters. Express your answer in centimeters. ▸ View Available Hint(s) 39 inches 99 cm Previous Answers ✓ Correct Part C What is the speed, in miles per hour, of a car that travels at 2.70 m/s?
