An 85.0 kg fisherman decides to jump from his boat onto the dock. If the velocity of the fisherman is 4.30 m/s to the
west and the boat is 185 kg, what is the velocity of the boat after the fisherman jumps out?
conservation of momentum applies
Massman*velocityman+massboat*velocityboat=0 Remember, the initial momentum of both was zero.
