Answer:
B) g downward
Explanation:
There is only one force acting on the ball during its entire motion: the force of gravity, which pulls the ball downwards. The magnitude of the force of gravity is
[tex]F=mg[/tex]
where m is the mass of the ball and g is the acceleration due to gravity. Using Newton's second law, F = ma, we can find the acceleration of the ball as:
[tex]a=\frac{F}{m}=\frac{mg}{m}=g[/tex]
so, the acceleration of the ball is g, and it is downward (as the force of gravity).
