3) While flying horizontally in an airplane, you notice that a string dangling from the overhead
luggage compartment hangs at rest at 15° away from the vertical toward the front of the plane.
Using this observation, you can conclude that the airplane is
A) accelerating forward.
B) moving backward.
C) moving forward.
D) not accelerating because the string is at rest.
E) accelerating backward.
Please help I am stuck!!!!!!

Respuesta :

Answer:

A

Explanation:

the string would be dangling backwards because you are moving forward it would be putting backward force on the string

The airplane must be accelerating backward.

  • The string performs another 15-degree turn more toward the aircraft's midsection. This same will indicate that a pseudo force exists exerted on it around the front of the aircraft.
  • Because pseudo force works throughout the opposing orientation of the movement.

Thus the response above i.e., "Option E" is the appropriate alternative.
