all you need to do is usee enough force to reach escape velocity. there is no speed needed.
oh dear your embarrassing your self. You have no clue on basic physics. doh

just so you know force equals mass times acceleration. Acceleration is the ratio of velocity over time squared. (Velocity as far as you're concerned is speed).
So if all you need is force to escape earths gravity i would agree, however this is not different from speed as you understand it.
If you still don't get this i would suggest another year in high school. Sorry to be so patronising but I don't appreciate being called an idiot.

my apologies youngster. Didn't mean to talk down to you. But I am really not wrong trust me I am a former school teacher. In order for the apollo space mission to achieve orbit it had to reach 20,000+ mph. It is the same for the hulk except he had to do it instantaneously not after 20 mins of fuel burn. 🙂
That's what was bugging me about the equation... Servance didn't write out what Velocity was, I knew distance factored in.
F=M*A
A=V/T
V=D/T
The question I was having was how much force would it take to move a 20,000ton ship? Suppose a character is moving the ship, but very slowly.
Say 0.89408 m/s since that's the distance over time that's the velocity if that remains constant would that be 0.89408 m/s²?
Times the mass of the ship it'd take about 16221914.6 newtons of force. But you still might not be moving very fast... The bulk of the number came from the MASS side of the equation rather than the ACCELERATION side...
That might be the problem Gecko is having with your solution Severance. You've placed everything into the speed side so that nothing is needed for the mass side. The mass side should be the gravitational forces that he's working against. Now would that be the standard "Weight is the measurement of gravitational force" and thus the Hulk's weight? Or would with Newton's third law of motion the Hulk jumping be like the Hulk pushing the planet away from him and thus be the Earth's weight? This is the Hulk after all...
i would like to add here that to reach orbit an object needs to have an initial speed of about 7miles per second. The speed is independent of mass of the object. This figure is if there is no further propulsion(like in a rocket). This figure is also based on the assumption that there is no atmosphere(so no friction). When we include atmospheric friction the speed has to be higher.

Hulk smash puny physics. 😂durhulk

ditto!oh and does Newton's Third Law mean we now have a feat of Hulk pushing the Earth (with his feet!) 😄

The number's been found out by theoretical means. It is based on the fact that Energy is constant. so Kinetic Energy + gravitational potential energy on earth = the same in orbit. i can explain further if you want but it is pretty boring stuff. 🤓

Why didn't you just use the number with air put in in the first place? Obviously in the example given it's hulk jumping out of Earth's atmosphere. As the mass of the planet would also be a number that would change. For example it doesn't take as much force to escape it's gravity.
And if I found this stuff boring I'd still be talking about the more direct relivence of which fictional character can beat which fictional character in a sterile setting that you don't really see in comics.
