A 70-kg fisherman in a 138-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.8 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.

15*4.8+(70+138)v2=0

72+208v2=0

v2=2.88m/s to left

This problem was done wrong. same equation but the answer was solved incorrectly. Your solving for v2. so 72 should be divided by the 208 not the other way around. The answer should be less the 1. around 0.346.
