A 1500 kilogram railroad car is moving with a velocity of 4.0 meters per second in a direction that is 20° north of east.
In the diagram below, starting from point P, draw a vector
that represents the railroad car's momentum using a scale
of 1.0 centimeter = 2.0 x 10 kilogram-meter per second.

If a star is moving toward earth, it is
