Question:

A 4.0 kg particle moves in an xy plane. At the instant w\en the particle's position and velocity are V = (2.0 i + 4.0 j) m and v = - 4.0 j m/s, the force on the particle is F = - 3.0i N. At this instant, determine
(a) The particle's angular momentum about the origin,
(b) The particle's angular momentum about the point x = 0, y = 4.0 m,
(c) The torque acting on the particle about the origin, and
(d) The torque acting on the particle about the point x = 0, y = 4.0 m.
