The figure below shows a fisherman in a canoe on a lake. The fisherman's mass is 71 kg, and the canoe's is 122 kg. The fisherman and canoe are initially at rest when the fisherman throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.6 m/s. What is the velocity of the canoe after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s,...
