As a continuation of the 1st question, let's assume that we find the required engine power P=3 kW while pulling the wagon up in the wagon system in Kardemir. Let's wrap the rope around the drum at v=7 m/s while pulling the wagon up steadily at the desired speed (don't take anything from the 1st question. Just think of it as a continuation).
