Asked Nov 6, 2019

The figure below shows a man in a rowboat on a lake. The man's mass is 73 kg, and the rowboat's is 113 kg. The man and rowboat are initially at rest when the man throws a package of mass

m = 15 kg

horizontally to the right with a speed of

vi = 4.8 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.)

magnitude

m/s

direction

Step 1

Given values:

Mass of the man, m_{1} = 73 kg

Mass of the rowboat, m_{2} = 113 kg

Mass of the package, m = 15 kg

Speed of the package, v_{i} = 4.8 m/s

Le the velocity of the package be V

Step 2

From the conservation of momentum:
