USS Enterprise warp 1.71 2030 yd/h

USS Enterprise warp 1.71 2030 yd/h

 

 

Science fiction often uses nautical analogies to describe space travel.

If the starship U.S.S. Enterprise is traveling at warp factor 1.71,

what is its speed in knots and in miles per hour?

(Warp 1.71 = 5.00 times the speed of light;

speed of light = 3.00×10^8 m/s; 1 knot = 2030 yd/h.)

우주선(starship)의 속도

= 5.00 × (3.00×10^8 m/s)

= 1.50×10^9 m/s

 

 

 

> 1 in = 0.0254 m (exactly, 정확한 값)

> 1 yd = 36 in

( 참고 https://ywpop.tistory.com/20863 )

 

> 1 h = 3600 s

 

 

 

(1.50×10^9 m/s) (1 in / 0.0254 m) (1 yd / 36 in) (3600 s / 1 h)

= (1.50×10^9) (1 / 0.0254) (1 / 36) (3600)

= 5.9055×10^12 yd/h

 

 

 

(5.9055×10^12 yd/h) (1 knot / 2030 yd/h)

= (5.9055×10^12) (1 / 2030)

= 2.91×10^9 knot

 

 

 

답: 2.91×10^9 knot
