1. A man is sitting on a train with a constant velocity of 10 m/s East. The man then stands up and walk backward with a velocity of 2 m/s. (a) Did the man's velocity with respect to the Earth change? (b) If yes, did it become faster or slower? (c) calculate the relative velocity of the man with respect to the Earth.
