How do you calclulate magnitude and dirction?

In the dark in outer space, you observe a glowing ball of known mass 3.2 kg moving in the xy plane at constant speed in a circle of radius 6.5 m, with the center of the circle at the origin (< 0, 0, 0 > m). You can't see what's making it move in a circle. At time t=0 the ball is at location < 6.5, 0, 0 > m and has velocity < 0, -35, 0 > m/s.

A) At time t=0, what is the direction of the momentum vector?
B) At time t=0, what are the magnitude and direction of the parallel component?
C) At time t=0, what are the magnitude and direction of the perpendicular component?
D) At time t=0, even though you can't see what's causing the motion, what can you conclude must be the direction of the Fnet vector?
E) At time t=0, even though you can't see what's causing the motion, what can you conclude must be the Fnet vector?
F) You learn that at time t=0, two forces act on the ball, and that at this instant one of these forces is F_1 = < 120, 542, 0 > N. What is the other force F_2?
