An object is thrown upward with a speed of 20m/s near the surface of a planet where the gravitational field strength is a constant magnitude of 6N/kg. The vertical position versus time of the object is shown in the graph. Is the object considered to be in free fall?

A. Yes, because the only force exerted on the object is the force due to gravity from the planet.
B. Yes, because any object that falls is considered to be in free fall.
C. No, because the object does not fall with an acceleration of nearly 10m/s2.
D. No, because the object has an acceleration due to gravity that is different from the gravitational field strength of the planet.
