Answer to Question #22830 in Mechanics | Relativity for matt

Question

——since the question states that East is pos-
itive, and the fisherman is moving west, then
when the fisherman jumps into the rowboat,
they will both be moving west. Therefore the
velocity should be NEGATIVE.——
Note: Take East as the positive direction.
A(n) 80 kg fisherman jumps from a dock into a 129 kg rowboat at rest on theWest side
of the dock.
If the velocity of the fisherman is 4.7 m/s
to the West as he leaves the dock, what is the
final velocity of the fisherman and the boat?
Answer in units of m/s
