A 2.0 kg particle-like object moves in a plane with velocity components v x = 30 m/s

Question:

A 2.0 kg particle-like object moves in a plane with velocity components v x = 30 m/s and vy = 60 m/s as it passes through the point with (x, y) coordinates of (3.0, - 4.0) m. Just then, in unit-vector notation, what is its angular momentum relative to
(a) The origin and
(b) The point (-2.0, -2.0) m?
