Emma is riding on a train. the train is moving at 50 m/s. emma walks down the aisle at 1 m/s relative to the train in the same direction the train is moving. what is her relative velocity? also, i know the equation for relative velocity is "t = δx ÷ v" but how would that fit into this type of equation? ? show your work!

low speed means non relativistic.

the velocities relative to an observer outside the train are added.

51 m/s.

Were ita light wave, rather than Emma, the speed wold not depend on the speed of the train. Though that may sound surprising, I think it's true. Special relativity says more about this.

Special relativity "shows up" when the speeds get very high indeed.

option number c is the right answer.
