Homework Statement
Scenario: a block of mass 5 kg is hanging from a spring from an ideal pulley from one side, the other side supporting a mass of 10 kg through a STRING.
Now, the 10 kg block replaced with a 5 kg block.
In which case would the extension in spring be greater, assuming constant acceleration.
Homework Equations
10(g-a)=5(g+a) - kx1
and
5(g+a)-kx2= 5(g-a)
The Attempt at a Solution
I know the answer is the first case, visualising it(and according to the solution). But I'm not able to prove this mathematically. From my equations I'm getting x1 proportional to (15a-5g) and x2 proportional to 10a and i don't know how these are related.
Thanks for the help :-)
