Draw a sketch of one of the shapes the class created with the drips from the swinging pendulum in problem 7-1.

1. Sketch what the shape would look like if the bag were pulled out farther before it was let go.

   Hint (a):

   Since the bag would swing farther each time, the shape would be stretched vertically.

2. Sketch what the shape would look like if the paper underneath the pendulum traveled faster.

   Hint (b):

   Since the paper would cover more distance per swing, the shape would be stretched horizontally.
