momentum is conserved
package mass * velocity = (boat + man) mass * velocity
as you have deduced, the velocities are in opposite directions
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.
