Answer:

C) The magnitude and direction

Explanation:

Velocity is a vector quantity, meaning that it has both magnitude and direction.

For the momentum, we look at both the direction of the ball (negative, positive) and the magnitude of the velocity (5 m/s, 10 m/s) when figuring out what to use for "v" in p = mv.
