divine retardation

>>12461890
This kind of thing isn't covered in high school, I'm trying to figure out stuff for a story I'm writing.

>>12461878
Jesus Christ op
Distance (Earth to mars) =112 million km
Speed (0.9c) = 270,000km/s
Time = distance/speed = 414s or 6min 54s

>>12461939
fag don't help the retards

distance/speed=time

Read the textbook again.

>>12461878
this is a fucking division problem you hopeless retard

>>12461921
then say so. You might as well carve Retard on your forehead with a hunting knife.

Retard.

>How fast would travel at 0.9 c be?
Post nudes of that girl I will tell you what 90% of 3x10*8 m/s is

>>12461921
this isnt even a high school problem, this is an elementary school division and multiplication problem

jesus christ anon

posters like OP should be banned on sight from /sci/ for not reaching the minimum IQ requirement

All those in favour say 'Aye'.

does nobody in this thread know special relativity? jesus christ

6 min to observer on Earth, seconds to you on the spacecraft

>>12461997
>implying you need to understand special relativity to answer OP's basic mechanics question.

>>12461878
3 seconds

>>12461997
Relativistic effects arent even big enough to be called a rounding error at 0.9c
You need to start hitting 0.99c

>>12462244
>Relativistic effects arent even big enough to be called a rounding error at 0.9c
Wrong. At 0.9c, time on board the craft should pass at about 43% of the rate it would for the observer.

>>12461878
>How fast would travel at 0.9 c be?
exactly 0.9c
low IQ thread

>>12461878
you can not do this, it's a short distance, acceleration would crush you and your ship, hitting a rain of sand on your way would crush you and your ship, also you would need an insane amount of energy

bottom line, you don't travel this fast within the solar system
