A 68-kg fisherman in a 136-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.0 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.

  1. momentum is conserved

    package mass * velocity = (boat + man) mass * velocity

    as you have deduced, the velocities are in opposite directions
