A feather, initially at rest, is released in a vacuum 12 m above the surface of the Earth.Which of the following statements is correct?
A)The maximum velocity of the feather is 9.8 m/s
B)The acceleration of the feather decreases until terminal velocity is reached
C)The acceleration of the feather remains constant during the fall
D)The acceleration of the feather increases during the fall
E)The acceleration of the feather is zero

Question

Quizplus · Accepted Answer

The acceleration of the feather remains constant during the fall due to the acceleration due to gravity, which is approximately 9.8 m/s^2 on the surface of the Earth. In a vacuum, there is no air resistance to alter the acceleration.
