Refer to Diagram of Billiard Balls F, K, M, and T

Refer to diagram of billiard balls F, K, M, and T. Each arrow represents the velocity of the ball. If billiard ball M is traveling straight upward at 2.5 m/sec, then

A) billiard ball M must be faster than T.
B) billiard ball F is the slowest of the four.
C) billiard ball K has the same velocity as M.
D) nothing about their speeds can be said, because they are all moving in different directions.
