Two trains are moving with velocities `v_1 = 10 ms^-1 and v_2 = 20 ms^-1` on the same track in opposite directions. After the application of brakes if their retarding rates are `a_1 = 2 ms^-2 and a_2 = 1 ms^-2` respectively, then the minimum distance of separation between the trains to avoid collision is
