    Laws Newton
AI Thread Summary
The discussion revolves around a physics problem involving Newton's laws, specifically relating to two masses, m1 and m2, and their acceleration. Participants debate the correctness of the acceleration being 2a and the relationship between the distances of m1 and m2. One user suggests that the masses are in equilibrium, questioning the initial assumptions about their values. The equations provided do not seem to yield the expected answer of a = 2.8, prompting requests for clarification on the setup. The conversation highlights the importance of verifying mass values and understanding the implications of equilibrium in solving the problem.

So t =T1. Why is the acceleration 2a in the second equation?
 
yes T1=t

and m1 distance double m2 distance that`s why the acceleration proportion is 2:1

is that right ?

No that's not correct where did you get that idea?
 
can you be more specific , what is not correct and how to solve the problem ?

I don't see anything wrong with your equations. Solve them to find a.

t-m_1gsin30=m_1*2a \ *2
+
m_2g-2t=m_2*a


m_1=m_2 = 5kg


2t - 2t - 2*5*0.5g + 5g= 20a+5a

0=25a ====> ?


the answer in the book is a=2.8

how is that ?



pleasez help .
 
Oops. It looks like the masses are in equilibrium if they are equal. Are you sure you have the masses correct? (Also, what book are you using?)

yea i am sure .

the book is classical mechanics by yoram eshel .
