positive

Explanation:

The ball is rolling down with a negative velocity, but the velocity is slowing down. therefore the velocity must increase in order for the ball to slow down.

For example let the ball's initial velocity be - 15 m/s. and it is slowing down to let's say - 13 m/s. Well this means that it's velocity has increase by 2 m/s. So, its acceleration is positive.
