Which is a possible measurement of the momentum of a moving object? 11 kg∙m2/s2 2.8 kg∙m/s 16 kg∙m/s, due west 9.3 m/s2, due north

16 kg∙m/s, due west

Explanation:

Momentum is a vector, whose magnitude is defined as the product between the mass of an object (m) and its velocity (v):

and whose direction is given by the direction of the velocity.

Let's analyze the units of measurement of the momentum. The mass is measured in kilograms (kg), while velocity is measured in meters per second (m/s), so momentum is measured in:

This leaves us with only two possible choices:

2.8 kg∙m/s

16 kg∙m/s, due west

However, since momentum is a vector, we must also specify its direction, so the only possible correct choice is

16 kg∙m/s, due west
