Chapter 11, Problem 26P

At the instant of Fig. 11-40, a 2.0 kg particle P has a position vector $\stackrel{\to }{r}$ of magnitude 3.0 m and angle θ₁ = 45° and a velocity vector $\stackrel{\to }{v}$ of magnitude 4.0 m/s and angle θ₂ = 30° Force $\stackrel{\to }{F}$, of magnitude 2.0 N and angle θ₃ = 30°, acts on P. All three vectors lie in the xy plane. About the origin, what are the (a) magnitude and (b) direction of the angular momentum of P and the (c) magnitude and (d) direction of the torque acting on P?
