Answer:
A. The object is accelerating.
Explanation:
Terminal velocity is the maximum velocity reached by a free falling object, and is determined from the characteristics of the object and the fluid in which it is immersed.
When sturdy objects are free falling, there will be a force on them, called drag force, produced by the upwardly directed air resistance that gradually increases its modulus from increasing body velocity.
Free fall is a uniformly varied movement, its acceleration is constant and equal to 9.8 m / s2 (at sea level), called gravitational acceleration. On fall, the modulus of body velocity increases, movement is accelerated, and therefore the acceleration signal is positive. t is the fall time.
For this reason, we can say that an object traveling at terminal velocity is constantly accelerating.
