AI Thread Summary
The discussion focuses on determining the acceleration of mass m2 in a pulley system using Newton's laws of motion. Participants question whether the acceleration values for both objects in the system are the same and discuss the implications of including or ignoring the mass and rotational inertia of the pulleys. There is a suggestion to verify the results by substituting the acceleration back into the equations for tension T1 and T2. Clarification is sought regarding the complete problem statement and the assumptions made about the pulleys. The conversation emphasizes the importance of considering all forces and components in the system for an accurate solution.

Is it right?

As a check, plug in your result of a=-g back into your Newton-Law equations to get expressions for T1 and for T2.
Are those results consistent with what you claim about how T1 and T2 are related?

Are the a's the same for the two objects? Can you justify your answer?
 
I thing it's incorrect. How should I solve it?

What is the complete statement of the problem?

Can we ignore the rotational inertia of the pulleys? How about the mass of the pulleys? It looks as if one of them has mass, m .
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
