A train crusing at a constant velocity Vt related to the ground. A person initially at rest(relative to the train) starts running and gains relative speed V0 after a duration Dt. if the person would have started from rest on to the ground, would the magnitude of impulse exerted on the person during Dt would be smaller ,equal ,or larger than the impulse needed to cause the same change in relative velocity in the same interval on the moving train ? assume that the person motion is in the direction of motion of train.
