Answer:
a) No. If air resistance is ignored the acceleration of the ball is the same at each point on its flight.
(b). No. As long as the air resistance is negligible, the acceleration of the ball at the top of its flight different from its acceleration just before it lands.
Explanation:
This constant, similar acceleration is called the acceleration due to gravity and it is the acceleration of a body due to the influence of the pull of gravity alone.
Every object on the surface of the earth regardless of its mass is pulled towards the centre of the earth, especially when in flight. Whether flying upwards, or coming downwards, the pull of attraction towards the surface of the earth is the same!
The acceleration for the things way up is different than the acceleration for the things way down.
The gravity of the earth attracts every object towards its center of mass regardless the mass of object.
(A) When an object is moving up against the earth, the gravity attract it and slows down its velocity.
(B) At the top, ball the acceleration become zero, near the earth just before it hits the ground, the acceleration is highest.
Therefore, the acceleration for the things way up is different than the acceleration for the things way down.
