Question #118509

A 9.00 kg object, travelling South with a speed of 8.50 m/s, is moving towards a 12.0 kg

object that is moving East with a speed of 6.00 m/s. Determine the total momentum

object that is moving East with a speed of 6.00 m/s. Determine the total momentum

Expert's answer

The total momentum is the vector sum of all momenta. Assume that y-axis points northward, y-axis looks eastward:

We can find the magnitude of the total momentum:

The angle above x-axis (north of east) is

or 46.7° below x-axis (below east axis), or 46.7° south of east.
