A 1.53 kg particle with velocity = (9.44 m/s) - (4.84 m/s) is at x = 1.03 m, y = 6.67 m. It is pulled by a 2.10 N force in the negative x direction. About the origin, what are (a) the particle's angular momentum, (b) the torque acting on the particle, and (c) the rate at which the angular momentum is changing?
