A particle of mass 7 kg has position vector r = (2 x - 3 y) m at a particular instant of time when its velocity is v = (3.0 x) m/s with respect to the origin. a. What is the angular momentum of the particle? L = 63 kg my /s in the ? v direction xyz b. If a force F = 5.0y N acts on the particle at this instant, what is the torque about the origin? T 10 V N m in the ? v direction xyz
