Question #22830

——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
