Open this video of a boy sliding e across the ice. The screen shows a data table, a position against time graph, and a velocity against time graph. The symbols used are t for time, x for position, Vx for velocity, and ay for acceleration. Click the play button, and watch the video. Then study the position against time graph. What is the change in the motion of the boy? How do you know? Is the acceleration of the boy positive or negative?​

Answer:

Probably late but the change in motion of the man is in his speed, I know because every 0.2 seconds, he was gaining more distance as he was the previous 0.2 seconds. His acceleration positive because he was speeding up.

Answer:

The change in the motion of the boy is that he is on ice with something little friction and is moving downwards(slightly), this is all leading to him speeding up. The acceleration of the boy is positive.
