A train makes a journey in which at a point on its trajectory a speed of 80.0 km / h is measured towards the east, while half an hour later the speed is 65.0 km /h towards the east. Can you calculate the average acceleration in this half hour of travel? a) No, because we do not know the starting position or the final position of that half hour of travel. b) No, because we do not know how the direction of the train changed in the other moments of that half hour of travel. c) Yes, and it has a magnitude of 30.0 km/h?? westward. d) Yes, and it has a magnitude of 30.0 km / h²2? to the east.
