Example 1 : A man traveling in a train walks with a speed of 6 km/h with respect to train and opposite to the direction of movement of train. The velocity of the train with respect to ground is 80 km/h. What is the velocity of man observed by an observer on the ground? Solution:   Here ground is the rest frame -                    Train is the internal frame       -                    According to Galilean transformation,                                                        Here,
