Homework Help: Physics

Posted by Andre on Friday, July 30, 2010 at 3:32pm.

A 2.1 kg particle-like object moves in a plane with velocity components vx = 30 m/s and vy = 55 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

HELP!!! I dont know what to do or where to start, except with the angular momentum formula L=r X p=m(r X v. Would the formula l=rmvsintheta also be necessary here??
