A) Both the horizontal and the vertical components are constant.
B) Both the horizontal and the vertical components are accelerated.
C) The horizontal component is constant but the vertical component is accelerated.
D) The horizontal component is accelerated but the vertical component is constant.

Answer 2

Any ideas ? Remember in order to have acceleration ther must be a force

After the ball leaves the racket there is only one force, gravity, and it acts in the vertical direction only
