Ariver with 400 ppm of salt (a conservative substance) and an upstream flow of 25.0 m3 /s receives an agricultural discharge of 5.0 m3 /s carrying 2,000 mg/l of salt. the salt quickly become uniformly distributed in the river. a municipality just downstream withdraws water and mixes it with enough pure water (no salt) from another source to deliver water having no more than 500 ppm salt to its customers. what should be the mixture ratio f of pure water to river water?

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
