Question

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

Answer 1

choice 1 is a possible measurement of the momentum of a moving object?

Answer 2

Momentum is a vector, although we don't hammer on that. In order to completely describe a momentum, you need a magnitude AND a direction ... just like force and velocity.

So choice #2 is the magnitude of a momentum, without its direction.

Choice #3 is the full package, with both the magnitude and the direction.

Choice #1 has units of energy, and choice #4 has units of acceleration, so neither of those can be it.
