an 85kg fisherman jumps from a dock into a 135kg rowboat at rest on the west side of the dock, if the velocity of the fisherman is 4.3m/s to the west as he lives the dock, what is the final velocity of the fisherman and the boat?

Ur dad.

momentum of the system is conserved, so (ignoring the very real resistance of the water) 4.3*85 = (85+135)v v = 1.66 m/s

K · Answer

why are the man and the boat's final velocity the same?

The fisherman is jumping into the boat so their masses become combined as they are one "object".
