As the ball rolls from A to B, its velocity increases, indicating that its acceleration is also increasing. Therefore, the correct choice for the first question is A, and for the second question, as the velocity of the ball starts decreasing while moving from B to C, its acceleration must also decrease. Hence, the correct choice is E.
