Light travels at a speed of 300000km per second. If you are traveling in a car towards the light at a speed of 100km per hour and you look left outside of your window how fast would the light be traveling by you?
(the answer is simpler than it seems)

ReplyDelete300 000km/s
ReplyDelete100km/h --- 100/3600= 1 sec.
therefore: 1/36 km= 1 sec
1/36 X 300 000 = 8333.3
AHHHH I HAVE NO IDEA!!!!!!!
lol, guess i've already failed physics :P
btw, guess u beat me to it this time :) Nice work. P.S= how did u get the 2nd question???
*** that question was for james ***
ReplyDeletelol, james might be wrong so...
ReplyDelete300000km per second = 1079252850 km per hour. seeing as your going towards the light at 100 km per hour then it should be 1079252950 km per hour or 300207.514 km per second.
other answer is 299792.486km per second.
lol, just to cover my butt. if your travelling toward the light and you look to your left. the could be no light because your not facing it anymore. Just saying in case Mr. P. is trying to trick us.
ReplyDeletei know im wrong... cos i fail
ReplyDeleteis the answer 300000km because the speed of light doesnt change
ReplyDeletebecause Theoretical Basis for Special Relativity
ReplyDeleteEinstein's theory of special relativity results from two statements -- the two basic postulates of special relativity:
1. The speed of light is the same for all observers, no matter what their relative speeds.
2. The laws of physics are the same in any inertial (that is, non-accelerated) frame of reference. This means that the laws of physics observed by a hypothetical observer traveling with a relativistic particle must be the same as those observed by an observer who is stationary in the laboratory.
300000km

ReplyDeletewell the speed of light in km/h in this case would be: 1 080 000 000
ReplyDeleteso the light is moving at the above.
and the car is moving at 100km.
so maybe 1 080 000 100km/h.
but i reckon thats really really wrong.
wheres paul and monica when you need them ayye?
300000.0278km/s???
ReplyDeletedo we have to show working out???D:
ReplyDelete100km/h = 1/36km/s
300000 + 1/36 = 300000.0278
man~ why is everyone different...=0=;;
soro's ones correct
ReplyDeletei got mixed up converting hrs into seconds..
soros ones correct "I think"
i know soro wrote this but... ill just do it with out looking at her working out
ReplyDelete100km / 1 hr = speed of car
to match up with km/s i times 1 hr with 3600
100 km / 3600 sec = 1/36 speed of car
speed of car + speed of light = 300000.02777803498 = 300000.03 km/s
1080000108 km/hr
i told you the answer on msn....=0=;;
ReplyDeletelol~ it would be sooo funny if we were wrong~xD
Good job guys.
ReplyDeleteAlana and Jessica are correct. Unlike sound light has a very special property that it's speed doesn't change when you are moving towards are away from it. This is what Einstein's special theory of relativity is based on.
Don't worry if you don't get this. I just wanted to make you think a little.
Mr. Pattison
to everyone (including myself) who got this wrong:
ReplyDeleteEPIC FAIL!!!
just wanted to do that.
