Originally posted by h1a8The math is wrong. SS could have hit 10,000,000X speed of light instantly, not accelerate any further and get to Thanos' raised hand in approximately 3 seconds. Or he could have stood nearly still for 2 seconds and then instantly accelerated to 30,000,000X speed of light to make up for lost time and again, get there in approximately 3 seconds. Or any varying number of combinations.
That's average speed not instantaneous speed. Plus the number is off, it's more like 10,512,000 (not 10,752,688).Do the math and u will see that he didn't reach light speed within the first 3m of travel.
I'll do it for you. First lets find the acceleration. Let D be the distance of a light year in meters, 'a' the acceleration in meters per second^2, and t for time in seconds.
D=299792458*3600*24*365
t=3Now
D=1/2at^2
=> a=2D/t^2Now that we know 'a' we find the speed Vf SS reached after the first 3 meters of travel.
Vf^2=2ad where d=3 meters
meters per second
=>Vf=sqrt(2*a*d)
=sqrt(2*2*D/t^2*d)

Light speed is 299792458 meters per secondSo SS obtained 37.45% of speed of light within after the first 3 meters of travel. [/B]
You're assuming a constant rate of acceleration (if you're even doing that). There is no mathematical equation for determining exact acceleration based only on total distance and total time travelled.
