You are on a train traveling east at speed of 29 m/s with respect to the ground.

Question

You are on a train traveling east at speed of 29 m/s with respect to the ground.

1)If you walk east toward the front of the train, with a speed of 1.7 m/s with respect to the train, what is your velocity with respect to the ground?

2)If you walk west toward the back of the train, with a speed of 2.5 m/s with respect to the train, what is your velocity with respect to the ground?m/s east

3)Your friend is sitting on another train traveling west at 25 m/s. As you walk toward the back of your train at 2.5 m/s, what is your velocity with respect to your friend?

Explanation / Answer

1)If you walk east toward the front of the train, with a speed of 1.7 m/s with respect to the train, what is your velocity with respect to the ground

Velocity subtracts =29-1.7 =21.9 m/s

2) If you walk west toward the back of the train, with a speed of 2.5 m/s with respect to the train, what is your velocity with respect to the ground

veocity adds up i.e 29+2.5 =31.5 m/s

3) Since you are moving toward each other, Your velocities will add up.

29 + 25= 54 m/s
