Main Question or Discussion Point

I'm trying to help my high school kid solve some momentum problems, and one of us must be missing something simple. The question is "What has more momentum a Mack truck (ie, very large object) that is still or a small truck that is moving?" I thought that momentum=mass*velocity. If this is the case, then the Mack truck would have a 0 and the small truck would have a positive number. However, my kid tells me the answer is the Mack truck. Am I missing something?

Thanks in advance.

your are correct
movementum is defined as

P = mv

where P is linear movementum, m is mass of object and v is velocity.
