The tanker has a weight W and is traveling forward at speed v₀ in still water when the engines are shut off. If the drag resistance of the water is proportional to the speed of the tanker at any instant and can be approximated by F_D = cv, determine the time needed for the tanker’s speed to become v₁. Given the initial velocity v₀ through what distance must the tanker travel before it stops? Given:
