a) The animation shows the ball moving at a constant speed until around .8 seconds, where it accelerates until the end of the animation. b) Graph A is correct, since it is the only one that shows the correct position vs. time graph. Graph B shows the ball having a smaller slope after the ball accelerates, and Graph C shows a jump in postion that is not possible. c) Graph F is correct. Graph D shows a jump in velocity that is not possible, and Graph E shows the constant speed of the ball as having a positive slope.
