Ariane 5

Actually, top fuel dragsters do 0-100mph in 0.8 seconds. Even better.

Do you think that much detail matters in this case? The point is, it looks like its accelerating slow because it is. How slow is slow? Thats the point im making, its what your comparing it to that makes it look slow. Of course its not going up as slow as it looks, but like I said before its not a sounding rocket, nor does it have a crazy power to weight ratio. A top fuel dragster accelerates much faster. 0 to 100mph in 1 second. No rocket that carries humans can claim the same.

Acceleration a = F/m = (2*1454510)/(1712000/32.2) -32.2 = 22.5 ft/s^2,
if using two main boosters. Do the math yourself if you know the details better (how many engines and how large the thrusts are). Details might be found from here

Predator45 your way wrong. Space Shuttles and large rockets are going slow on liftoff, its not an illusion. The reason's are simple, G-force tollerance(astronaughts are fragile), insane weight(SRB's burn 11,000lb of fuel each per second so they get light quick), and purpose(the shuttle is not attacking an incoming nuke like the Nike Sprint did, which accelarated at 100g's to mach 10 in 5 seconds, speed and force that would kill anyone. Sounding rockets and such have very high power to weight ratio's, the shuttle and Araine does not. Get your facts strait.

Thanks Predator. That's what I thought...

As you say:,,Why are rockets and space shuttles allways so slow in the beginning of their launch...,, they are not slow.In the beginning they're reaching crazy speed.It just looks like rocket is slow.Do you know how big is that metal construction near the rocket that goes away when the rocket tkes off? :) So speed is very big.I din't know... maybe you were talking about that slow motion.Hope you goit your answers.

Snakes*** : same for me...

Anyone who can, please tell me:
Why are rockets and space shuttles allways so slow in the beginning of their launch? They nearly seem to stand still while spitting out a lot of flames and smoke. I've wondered about this a while now...

Just Awesome!!!!!!!!!!!

It Rocks!!!!
