I'm trying to find the speed of light squared (in metres per second) which is
89875517873681764 * 89875517873681764
and I get
8.0776087e+33
This means nothing to me nothing to me can someone explain it
Tnx...
ps: the answer should be
8077608713062490229263800746151696
Relativity. Closing speed is actually (u + v) / (1 + (uv / c^2))I am not up on my math, but why? Surely if they are driving directly towards each other it's 2x100km/h?
If your trying to be 100% correct then no.Surely if they are driving directly towards each other it's 2x100km/h?
that makes no sense to me...
All of itWhich part?
c is a constant, the speed of light. The example was if both objects were travelling at half of the speed of light. If you look at my image, when you feed two objects travelling half of the speed of light in to the equation, the result is a closing speed of 80% of the speed of light.All of it
v1=v2=c/2
he's saying c is twice the other values
so v1 = v/2
and v1 = c/2
and v2 = c/2
If v1 is 100kmh then c is 200kmh because if you divide it by 2 you get v1 and thats just wrong
yes but your equation is very different than
v1 = v2 = c/2.
Being a pedant here but the speed of light squared will in m^2/s^2 not m/s. >8->I'm trying to find the speed of light squared (in metres per second)
Absolutely correct from the perspective of either object! To either one of them, the other object is in every way approaching at 80% of the speed of light.This means that two objects, each travelling at half of the speed of light, end up moving towards each other at 80% of the speed of light.
