Two particles whose masses are equal to m1 and m2 (m1 > m2) move towards each other along the same straight line with the same speeds. After an elastic collision, a heavy particle deviates from the direction of its initial motion by an angle a = 30° in the laboratory frame of reference or by an angle b = 60° in the center of mass frame. Determine the ratio m1/m2.
