A particle P with mass 10 kg has position vector r (r = 3.5 m) and velocity v (v = 25.0 m/s) as shown in the figure. It is acted on by force F (F = 9.0 N). All three vectors lie in the xy plane. About the origin,
a)what is the z-component of the angular momentum of the particle?
B)About the origin, what is the z-component of the torque acting on the particle?
