A simple system of two masses and two pulleys

AI Thread Summary
The discussion revolves around solving a physics problem involving two masses and two pulleys, with the user seeking assistance in determining the correct expression for the acceleration of the masses. The user has attempted the problem multiple times but received different answers. A forum member emphasizes the need to see the user's work to provide effective help. It is pointed out that the assumption of equal accelerations for both masses is incorrect due to the constraints imposed by the rope's constant length. The conversation highlights the importance of understanding the relationships and constraints in the system to arrive at the correct solution.

mainly newtons second law
hey there,

I am confusing what is the right answer to this system of mass, I solved it a couple of time and I got different answers. can you help me with that?
I need to find the expression of the acceleration of the 2 masses.

thanks a lot,Adam.

on the left middle; if the system was stretch all the way. it will be easier to find the length equation, thanks a lot/

I see you somehow got that a1=a2. That is incorrect.

Consider that the rope attached to M2 is of constant length. That places a constraint on the relationship between a1 and a2.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
