Force is not momentum. Velocity is not acceleration. Let's find its momentum after 2 seconds:
p=mv
p=ma*t
1000000 x .00004 x 2 = 80Ns

Let's find its momentum after 1000 seconds:
p=mv
p=ma*t
1000000 x .00004 x 1000 = 40,000Ns


how long is the spring your using kallog?

because even if its 1000000 km long and you only compress it to 40N , 40N is all you can get out of it.

its just like compressing air into a air cylinder.

so when you say 1000 seconds it must be pretty long because its acceleration is only .00004 m/s/s

from what I can tell its 20 meters long.

if you applied a force of 40N over a distance of 20 meters to compress the spring.

or if you compress the spring in only 1 second using a force of 40N

then you can only get 40N out of it no matter how long it takes for the spring to expand.

so the spring expanded for a distance of 20 meters and then the solar sail just free floats.

because the spring is only 20 meters long.

so how did you end up with 40000N?

is it because the spring requires more force than 40N to compress?

perhaps it requires 40N per second if you compress it for 1000 seconds.

the above is why we shouldnt use momentum.

from now on I will use push and pull

to avoid the things that just dont make any sence to me.

a 40 kg push
a 40 kg / sec push

a 40 kg pull
a 40 kg / sec pull

replacing the word force with the word push or pull

so that I can say something like the following.

the 10 kg mass hit the wall at a velocity of 2 m/s with a push of 20 kg m/s.

the mass has a push of 50 kg m/s

the mass is accelerated to a velocity of 10 m/s/s
by a push of 500 kg m/s

push = mass x acceleration

500P = 50 kg x 10 m/s/s

push and pull replacing both force and momentum.
