A tennis player on serve tosses a ball straight up. While the ball is in free fall, does its acceleration a. increaseb. decreasec. increase then decreased. decrease then increasee. remain constant

Respuesta :

Answer: Remains constant

Explanation:

The acceleration of the body under the free fall always remains constant. A body falling freely after reaching its maximum height when launched is under the influence of gravitational force (g) and the value is positive for downward fall.

Note that the acceleration possessed by the body is acceleration due to gravity which is the same at any point during the fall i.e 9.81m/s².
