A 1.5 kg particle-like object moves in a plane with velocity components vx = 40 m/s and vy = 90 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? kg · m2/s (b) What is its angular momentum relative to the point (-2.0, -2.0) m at this same moment? kg · m2/s
