you can't just ignore C1. Maybe you could if it was something like a differential equation or integral equation (in terms of derivatives and integrals) but this is only an algebraic equation. v^2/2 = GM/(D-x)-GM/D v^2 = 2GM/(D-x)-2GM/D v = sqrt(2GM/(D-x)-2GM/D) v = sqrt(2GM) * sqrt(1/(D-x)-1/D)...

1st step... v^2 = A + B doesn't exactly imply v = sqrt(A) + sqrt(B) :B

I think you don't need to use torque. By F= m * a(center of mass) you get that their accel will only depend on forces applied to them. In both cases block and cylinder you have F = T - mg. Then => m * aBlock = m * aCylinder => aBlock = aCylinder

= \Sigma r^{n}, with r = (2+3i)^(2+i), but |r| = 4.86... > 1 \Rightarrow the sum diverges, so it doesn't even make sense to define it as a function (at least not in the traditional simple way). Therefore you can't take any derivative.
