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