Problem
Let us assume a pulley in a fixed position with a rope of negligible weight. A weight m1 is located on one end of the
rope and a winch (mass m2) on the other. Initially, the winch is in the same height as the weight m1. In the first case,
the winch is fixed to the ground and pulls only the weight. In the second case, the weight is firmly connected to the winch.
Therefore, while the rope is being attached, both the weight and the winch are pulled up. Find out which case requires less pull
force (and therefore weaker winch).
