The figure shows two 1.0 kg blocks connected by a rope. A second rope hangs beneath the lower block. Both ropes have a mass of 250 g. The entire assembly is accelerated upward at(adsbygoogle = window.adsbygoogle || []).push({});

3.0 m/s^2

i found the force that pulls the system to be 32.0N

However the followup question states:

What is the tension at the top end of rope 1?

for a I have

[tex]

\sum{}\ = F - T = ma

[/tex]

and for b I have

[tex]

\sum{}\ = T - W = ma

[/tex]

since i knew my a was 3.0 m/s^2 i made the equations equal to each other, to find my tention.

[tex]

(T - W)m = (F-T)m

[/tex]

I arived at the answer 25.1N which is wrong. i think it may have to do with the fact that the ropes have a mass I thought tension through out a rope was uniform no matter where on the string you are. :grumpy:
