A 9.99 kg particle with velocity v→ = (3.10 m/s)i^ − (6.83 m/s)j^ is at x = 2.73 m, y = 2.93 m. It is pulled by a 5.08 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 k^ Units (b) Number k^ Units (c) Number k^ Units
