The figure below shows a person in a rowboat on a lake. The person's mass is 82 kg, and the rowboat's is 138 kg. The person and rowboat are initially at rest when the person 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 rowboat 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.) i magnitude m/s direction ---Select--- Need Help? Read It
