Question

A flight attendant is standing in the middle of a plane. There are two signs. The front, F and the back, B. The flight attendant is precisely between them. The airplane is standing still relative to the airport this v=0. Which sign will the flight attendant see first? A) the sign in the front, F B) the sign in the back, B C) both at the same time The passengers are waiting at the gate. The plane is still, v=0. Which sign will the passengers see first A) the sign in the front, F B) the sign in the back, B C) both at the same time Now the plane is moving to the left. So v= 5mph, left. Which sign will the flight attendant see first now? A) the sign in the front, F B) the sign in the back, B C) both at the same time Question 2) Can either of us confirm when something happens simultaneously between two relatively moving inertial frames of reference?

Answer 1

Given data:

* The relative velocity of the airplane with respect to the airport is 0 m/s

Solution:

As the flight attendant is standing in the middle of the airplane or in the middle of the both the signs F and B. Thus the distance of both the signs from the flight attendant is same.

Hence, the flight attendant will see both the signs at the same time and option C is the correct answer.
