comment When should we use the concept of Impulse/Momentum instead of Force?
"Lets say you have a pulley system. A simple one: A person A is hanging from one end," I enjoyed reading the answer, until I read this peace of horror, specially that it's complemented with "and a block B of equal mass is on the other end.". Good, the person is dead in equilibrium.

but we can't find velocity without time, so I guess we need to know time anyway (if we could find time and velocity, we can find acceleration also.)
