A(n) 83 kg fisherman jumps from a dock into a 139 kg rowboat at rest on the west side of the dock. if the velocity of the fisherman is 3.1 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.

here we can say that there is no external force on fisherman and dock

so here we will use momentum conservation theory

As per momentum conservation

initial momentum of fisherman + boat = final momentum of fisherman + boat

now we will have

so the speed of boat and fisherman will be 1.16 m/s

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

answer; equivalent to a one(1) horsepower motor;
