Unformatted text preview: y direction. a) In unit-vector notation, what is the particle's angular momentum about the origin? By definition, the angular momentum of the particle is l = r m v =m(yv z- zv y ) i + m(zv x- xv z ) j + m(xv y- yv x ) k = -96(kg m 2 /s) j- 48(kg m 2 /s) k b) In unit-vector notation, what is the rate at which the angular momentum is changing? According to Newtons 2 nd law in angular form, the rate of change in the angular momentum of the particle is equal to the torque acting on the particle. d l /d t = = r F =(yF z- zF y ) i + (zF x- xF z ) j + (xF y- yF x ) k = 90(N m) k...
