A particle of 3.0 kg having velocity v = (5.0 m/s) ihat - (6.0 m/s) jhat is at x = 3.0 m, y = 8.0 m. This is pulled by a 7.0 N force in the negative x direction.
(i) Determine the angular momentum of the particle about the origin?
(ii) At what torque about the origin acts on the particle?
(iii) At what rate is the angular momentum of the particle varying?
