The mass of the body

attached to the movable pulley is 12 times the mass of the body fixed to the ground. At some instant the
body fixed to the ground is released. What will be the height that it can ascend? The heavier mass is initially h meter above the ground.

one has to know the mechanical advantage of the pulley system. if configured correctly, it could go to 12 h
The answer is 2h.
again,one has to know the MA
Tension T in rope,
on big mass
M g - T = M a

while the big mass is falling, the little mass goes up a distance h

when the big mass hits ground, the little mass is moving with the speed that the big mass hits with, then coasts up until the kinetic energy of that speed is spent. That is another distance h
Well, there is a picture to this question which shows that the tension on the bigger mass is 2T and the tension on the smaller mass is T.
