A 4.93 kg particle with velocity 3 (1.20 m/s )i (8.41 mls )3 is at x = 788 m, y = 7.26 m. It is pulled by a 8.90 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? (a) Number n E Units v (b) Number n 1; Units v (c) Number n 7; Units v
