Question

question # 1: when a fully loaded, a NASA crawler- Transporter (which isused to move the space shuttle) moves at a speed of roughly 2 km /hr and consumes 350 liters of fuel per kilometer. (a)      what is the crawler'sspeed in furlong per fornight? (note that 1 furlong = 1/8 mile and1 furlong = 2 weeks). (b)      what is the gasconsumption of the crawler in mpg (miles per gallon) and gallons /hour? Question # 2: Perform each calculation and write your answer using thecorrect number of significant figures. 1.            5.287- 5.13 =    2.             (4.566) / (1.35) = 3.            (3.94)+ 0.5 = Question # 3: Dimensional analysis problem: if x is measured in meters and t is measured in seconds, thenwhat are the dimensions of the constants b and c that will make thefollowing equation dimensionally correct?             x = bt3 + ct question # 1: when a fully loaded, a NASA crawler- Transporter (which isused to move the space shuttle) moves at a speed of roughly 2 km /hr and consumes 350 liters of fuel per kilometer.

Explanation / Answer

Question # 2: Perform each calculation and write your answer using thecorrect number of significant figures. 1.            5.287- 5.13 = 0.157 ~0.16           (2sig figs after decimal b/c of 5.13)
2.             (4.566) / (1.35) = 10.6255645 ~10.6          (three digits b/c mult and div so use 3 digits from 1.35)
3.            (3.94)+ 0.5 = 2.48494332 ~ 2.5   (most accurate is tenthsdigit because of 0.5)
Question # 3: Dimensional analysis problem: if x is measured in meters and t is measured in seconds, thenwhat are the dimensions of the constants b and c that will make thefollowing equation dimensionally correct?             x = bt3 + ct
