Question

You are on a train traveling east at speed of 18 m/s with respect to the ground. 1) If you walk east toward the front of the train, with a speed of 1.2 m/s with respect to the train, what is your velocity with respect to the ground?

Answer 1

19.2 m/s

Step-by-step explanation:

The train is moving at 18 m/s and you are walking in the same direction (east) so the speeds are added

18 + 1.2 = 19.2

If you were walking backwards (west) your velocity with respect to the ground would be

18 - 1.2 = 16.8
