Graphing a pulse on a string: 2

In the figure below is shown a photograph of a pulse on a taut string moving to the right. To the right of the figure is shown a small bead attached to the string.

For each of the following quantities, select the letter of the graph that could provide a correct graph of the quantity for the bead in the situation shown (if the vertical axis were assigned the proper units) and write it on your answer sheet. If none of the graphs could work write N.

  1. The vertical (up-down) displacement of the bead.
  2. The vertical velocity of the bead.
  3. The horizontal (left-right) displacement of the bead.
  4. The horizontal velocity of the bead.
