A 74-kg fisherman in a 124-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.4 m/s as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown.
