Ok, thank you. :)

Right, I don't think I have to do that much. To be 100% sure, it's ok?

Ok, thank you! But can I have one more question? How should I draw those forces at that picture? Should I draw Fs and Ft or only one of them? They should "touch" mass 2 or spring?

So... 0,1 = k*0,02 k=5 m1*a = m1*g - Ft m2*a = Ft - m2*g a(m1 + m2) = g(m1 - m2) a = 0,2/0,08 = 2,5 m/s^2 Ft = m2(a + g) = 0,03*12,5 = 0,375 = Fs 0,375 = 5*x x = 0,075 m x+0,1 = 0,175 m = 17,5 cm Is it correct?

Well, because of mass 1 that system is moving to the left.

I'm not sure but aren't second mass applying force? Can't Fg be force of action and Fs force of reaction?

Hym, I can solve problems when there is no spring. That spring is real problem since I don't know how to mark forces at that device. Is Fs=Fg? My friend tried to solve that without Fs but I'm not sure...

I'm Wiktoria, I come from Poland. I've created accounts here solely because I'm trying to get better mark and i have to solve a few extra problems. One of them comes from academic curriculum and I don't know how to do it. You can imagine how desperate I'm to create account this site even though...

Homework Statement m1= 0,05 kg, m2= 0,03 kg, mass of spring is omitted. We look at movement after spring stopped vibrate. How long does the spring measure during the movement if not stretched spring measure 0,1 meter and if we use force 0,1N elongation measures 0,02 meter. (sorry, English isn't...
