A particle of mass 4.0kg has position vector of (4.0i-3.0j) at a particular instant of time when its velocity 3.0i
with respect to the origin. (a)what is the angular momentum of the particle?(b) if a force of 6.0j N acts on the
particle, what is the torque about the origin?

Definition Definition Product of the moment of inertia and angular velocity of the rotating body: (L) = Iω Angular momentum is a vector quantity, and it has both magnitude and direction. The magnitude of angular momentum is represented by the length of the vector, and the direction is the same as the direction of angular velocity.
