Using dimensional equations, convert (a) 3 wk to milliseconds. (c) 554 m /(day-k

Question

Using dimensional equations, convert (a) 3 wk to milliseconds. (c) 554 m /(day-kg) to cm /(min-g). (b) 38.1 ft/s to miles/h. ds. (e) 554 m'(day kg) to P#2: Using the table of conversion factors on the inside front cover, convert (a) 760 miles/h to m/s (b) 921 kg/m2 to lb/It (c) 5.37 × 103 kJ/min to hp. P#3; You are trying to decide which of two automobiles to buy. The first is American-made.costs $14500. and has a rated gasoline milcage of 28 miles/gal. The second car is of European manufacture.costs 21,700, and has a rated mileage of 19 liver their rated mileage, estimate how many miles you would have to drive for the lower fuel km/L. If the cost of gasoline is $1.25/igal and if the cars actually consumption of the second car to compensate for the higher cost of this car? P#4: A) Solve the following equation using your calculator Using these initial guesses: 0, 0.5, 1, 2, 4. Explain B) Evaluate this integral using your calculator (5 x - 3*) dx C) Use your calculator to solve the following system of equation:

Explanation / Answer

Ans 1

Part a

Convert 3 weeks to milliseconds

= (3 weeks) x (7days/week) x (24 hr/day) x (3600s/hr)

= (1814400 s) x (1000 milliseconds / s)

= 1.814 x 10^9 milliseconds

Part b

Convert 38.1 ft/s to miles/h

= (38.1 ft/s) x (1mile/5280ft) x (3600s/h)

= 25.977 miles/h

= 2.598 x 10^1 miles/h

Part c

Convert 554 m4/(day-kg) to cm4/(min-g)

= 554 m4/(day-kg) x (100cm/m)4 x (1day/1440min) x (1kg/1000g)

= 3.847 x 10^4 cm4/(min-g)
