Problem 3.3: Rank the motion diagrams
Please wait for the animation to completely load.
The animations represent the motion of a ball on various surfaces (position is given in meters and time is given in seconds). The "ghosts" are placed at equal time intervals. Such a picture is often called a motion diagram. Restart.
Answer the following questions using the coordinate system specified in each animation by the red arrow. Please indicate ties by ( ). For example a suitable response could be: 1,(2,3),4,5,6.
For parts (a), (b), and (c), use the ghost images to qualitatively rank the quantities.
- Rank each case from highest to lowest displacement.
- Rank each case from highest to lowest final velocity.
- Rank each case from highest to lowest acceleration (assume constant acceleration).
Now use the usual x and y coordinates that you can access by click-dragging in the animation.
- Calculate the displacement vector for each animation.
- Calculate the acceleration vector for each animation (assume that in Animation 3 and Animation 6 the ball starts at rest and that in Animation 1 and Animation 4 the ball ends at rest).
