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?

19.2 m/s

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

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

we need to know the time interval during which the force acts. impulse of force = momentum change
