Question

A 74-kg fisherman in a 127-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.6 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.

Explanation / Answer

m1v1=m2v2
15*4.6 = (74+127)*v2
v2 =0.34328358209 m/s towards left
