If it were on a frictionless surface, the ball (or any object) would remain stationary relative to the ground and slide backward relative to the wagon, until it fell off the wagon (assuming there's nothing preventing that). But since the object is a ball, I'm guessing the question involves the ball rolling, which will happen if there is friction. In that case the ball won't remain stationary since it is being accelerated in rotation, and the tangential force needed to do that, applied through frictional contact, also accelerates the ball forward. The ball will move forward relative to the ground, but backward relative to the wagon.
So not enough information has been supplied for a definite answer.

A) the floor and B) the wagon ???????? what i be conscious of is once you push the eccelerator forward gravity could push the ball to the back of the wagon and once you hit the brakes the ball would be forced to the front of the wagon. the floor could i think teach marks from the wagons tires and the wagon could only shop going forward while making use of the accelerater forward regardless if the ball is interior the wagon or no longer.

Think about Newton's Laws... specifically, if the wagon accelerates forward and there is no force acting on the ball to accelerate it also...

It depends on how fast the acceleration is. The ball will roll backward or in relation to the ground stay in place.
