A pulley system reduces the effort of lifting a big bucket of water from a shallow well. The 100-newton bucket is lifted to a height of 5 meters with an unknown input force. If 50 meters of rope is pulled to lift the bucket the desired height and the percent efficiency of the pulley system is 78%, what must the input force be?
