Answer 3

Do you know what momentum is?

Answer 4

yes

Answer 5

Well, so it's the product of velocity and mass. But it's not just a number - it's a vector (as is velocity), which means that, in addition to the number, you also need to have its direction. In this case, it's the same as the direction of speed.
