Question picture:
My solution:
Where:
S is the lineforce
Ff is the force as a result of friction
a is the resulting acceleration
F is the acting force
The answear is supposed to be a=(F-2mg(mu))/(m+M)
Any idea what i could have missed?
Thanks for your help on beforehand!

I saw this trailer on ultra screen in 3d and I was captivated. No doubt a very well made trailer, but still I'm pretty stoked for the movie! Even if it just reaches the success of the first, it's been a nice series reboot.
