A 2.80 kg object moves in a plane with velocity components vx = 14.0 m/s and vy = -84.0 m/s as it passes through the point (x,y) = (0.7,-4.2) m.
A) What is the magnitude of its angular momentum relative to the origin at this moment?
B) What is the magnitude of its angular momentum relative to the point (-2.0,-2.0) m at this same moment?
