Ramu saw in a NEWS channel that a goods train of mass 200 metric ton moving with a velocity of 72 km h^(-1) collides with a passenger train of mass 300 metric ton with a velocity of 54 km h^(-1) coming in the opposite direction on the same track and both the trains move together after collision. He calculates their common velocity. Find what could be his answer.
