question

Let the acceleration of a non-inertial frame, a freely falling elevator, be a_O^\ding{217} = -g\^{y} where \^{y} is measured upward from the surface of the earth and g is the acceleration of gravity. Under these conditions, what is the net force acting on a mass M at rest in the elevator?

category

physics

options

  1. M is stationary relative to the Earth's surface
  2. M is falling at the same rate as the elevator
  3. M experiences twice the gravitational force
  4. M experiences a force equal to its weight downward
  5. M is weightless
  6. M is accelerating at g upwards
  7. M experiences a force equal to its weight upward
  8. M experiences a centrifugal force due to the Earth's rotation
  9. M is accelerating
  10. M is at constant velocity
