Answer

(a) The ball will land directly in the launching tube. (b) The ball will land behind the launching tube.

Work Step by Step

(a) The ball will land directly in the tube. The ball and the cart have the same constant horizontal velocity so the horizontal position will always be equal. (b) The ball will land behind the launching tube. After the ball leaves the cart, the cart accelerates forward with a faster horizontal velocity. Therefore, the ball's horizontal velocity will be less than the cart's horizontal velocity, so the ball will land behind the launching tube.
