Homework Help: angular momentum

Posted by jose on Wednesday, May 30, 2012 at 10:02pm.

a 8.20 kg particle P has a position vector of magnitude 6.90 m and angle θ1 = 42.0° and a velocity vector of magnitude 6.70 m/s and angle θ2 = 25.0°. Force , of magnitude 8.90 N and angle θ3 = 28.0° acts on P. All three vectors lie in the xy plane. About the origin, what are the magnitude of (a) the angular momentum of the particle and (b) the torque acting on the particle?
