Find x
Since the triangle is a 45-45-90 triangle, the following relationship exists
--- i.e. the other legs are equal
So, we have:

Divide both sides by 2

Take square roots of both sides

Simplify

D, small force for short time, as it has the least influence on the velocity.
C, momentum is velocity x mass, so if velocities are the same, then the object with less mass with have a lower momentum.
