The figure below shows a man in a canoe on a lake. The man's mass is 83 kg, and the canoe's is 121 kg. The man and canoe are initially

at rest when the man throws a package of mass m = 15 kg horizontally to the right with a speed of v; = 4.7 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, and select the correct direction from the options given.)
