Two particles, each of mass m and speed v, travel in opposite directions along parallel lines separated by a distance d.
(a) Find an expression for the magnitude L of the angular momentum of the twoparticle system around a point midway between the two lines. Use m for the mass, v for the speed and d for the distance of separation.

L = 2*m*v*(d/2) = m*v*d
