Question

2.18  

The doozy is defined as the unit of force required to accelerate a unit of mass, called the cuz, with the gravitational acceleration on the surface of the moon, which is one-sixth of the normal gravitational acceleration on earth.

(a)  

What is the conversion factor that would be used to convert a force from the natural unit to the derived unit in this system? (Give both its numerical value and its units.)

(b)  

What is the weight in doozies of a 3-cuz object on the moon? What does the same object weigh in Lizard Lick, North Carolina?

Explanation / Answer

2.18: From the given data,

(a) conversion unit

force(1 doozy) = mass x acceleration =

                        = 1 cuz x gravitational acceleration

                        = 1 x 9.8/6

                        = 1.63

(b) weigth of 3 cuz object on moon = 3 cuz

Same object weight in North Carolina = 3 x 6 = 18 cuz
