A boat turns off its engine while traveling at 10 m/s, and then a constant drag force slows the boat to a stop, while traveling an additional 80 m. The mass of the boat is 600 kg . What is the magnitude of the constant drag force, in Newtons, required to stop the boat in 80 m?

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
