Problem: A ball is thrown against a wall and bounces back toward the thrower with the same speed as it had before hitting the wall. Does the velocity of the ball change in this process? A) Although the speed is the same, the direction has changed. Therefore, the velocity has changed. B) The velocity is the same because the speed is the same. C) Without knowing the mass of the ball, the velocity is not determined. D) The velocity is now twice as large because the ball is going into the opposite direction.
