A 1.5 kg particle-like object moves in a plane with velocity components vx = 30 m/s and vy = 30 m/s as it passes through the point with (x, y) coordinates of (3.0, -4.0) m.
(a) What is its angular momentum relative to the origin at this moment?
(b) What is its angular momentum relative to the point (-2.0, -2.0) m at this same moment?
