A particle of mass 5.0 kg has position vector r → = (2.0i ^ − 3.0j ^ )m at a particular instant of time when its velocity is v → = (3.0i ^ )m/s with respect to the origin. (a) What is the angular momentum of the particle? (b) If a force F → = 5.0j ^ N acts on the particle at this instant, what is the torque about the origin?
