Question

An airplane is flying at a constant speed in a positive direction. It slows down when it approaches the airport where it's going to land. Which term describes the slowing of the plane?

A) stationary
B) positive velocity
C) positive acceleration
D) negative acceleration
E) constant velocity

Answer 1

(D) Negative acceleration (less and less speed)

Answer 2

Answer:

D

Explanation:

The right answer would be D because in the text, it says "It slows down when it approaches the airport where it's going to land." Which is not positive velocity, its not positive acceleration because you are slowing down, its not A because the plane is still moving, and it is not E because it is at a negative velocity (i think, dont quote me on it.)

Hope it helps.
