A hockey puck sliding on ice collides and rebounds from a wall on a hockey rink. A top view is shown in the above animation (position is given in meters and time is given in seconds).

Please answer the following questions:

For each of the following time intervals, calculate the displacement, distance traveled, average velocity, and average of the puck. Time intervals: 1.5s to 12.0; 1.5 to 6.0; 6.0 to 12.0.
For which time interval(s) listed in the table above is the displacement equal to the distance traveled?
Is the magnitude of the displacement always equal to the distance traveled?
In general, if an object moves in a straight line but does not change direction, will the magnitude of its displacement during any interval equal its distance travled during the same interval? If the answer is no, which will be greater?
In general, if an jobject moves in a straight line but changes direction at some point, will the magnitude of its displacement during an interval equal its distance traveled? If the answer is no, which will be greater?
Finally, qualitatively draw the acceleration vs. time graph for the animation.
