Question

I order to impart the greatest momentum to an object, you would?

Answer 1

Well, momentum is the product of mass and velocity. You can't change an objects mass, so what do you change?

And to you increase it or decrease it to give the object the greatest momentum?

Answer 2

In order to impart the greatest momentum to an object, you should both exert the largest force possible upon the object in question and extend that force for as long as possible.

Answer 3

That's another good approach, as the change in momentum is the product of the average force and the length of time that the force was enacted. I think that's a general case, but correct me if I'm wrong!
