Problem 2.4

Please wait for the animation to completely load.

Two balls are putted with the same initial velocity on separate greens.  The x axis is always defined to be parallel to the ground (even when the blue ball is on the hill). The first ball (red) rolls on a flat surface.  The second ball (blue) rolls on a flat surface, then down a hill, onto a flat surface, then up a hill, and onto a flat surface again (position is given in meters and time is given in seconds).

  1. Which ball will reach the hole first?  Make your prediction and then press "play" to view the animation to see the result.   Restart.
  2. Which ball has a greater average velocity during the animation time?
