Question

Felipe is on a train going south at 30 meters per second. At one point, he passes a train that is traveling north at 24 meters per second. From Felipe's frame of reference, what is the velocity of the northbound train

Answer 1

From Felipe's frame of reference, the velocity of the northbound train is 54 meters per second.

Step-by-step explanation:

In this scenario, Felipe is on a train traveling south at a velocity of 30 meters per second. He passes a train traveling north at a velocity of 24 meters per second. From Felipe's frame of reference, we need to consider the relative velocity of the northbound train.

To find the relative velocity, we subtract the velocity of the northbound train from the velocity of Felipe's train. In this case, we have:

Relative Velocity = Velocity of Felipe's train - Velocity of the northbound train

Relative Velocity = 30 m/s - (-24 m/s)

Relative Velocity = 30 m/s + 24 m/s

Relative Velocity = 54 m/s

Therefore, from Felipe's frame of reference, the velocity of the northbound train is 54 meters per second.
