Problem 2.14

Please wait for the animation to completely load.

Press "play" to see a putted golf ball roll on a green as shown in the animation (position is given in meters and time is given in seconds).   Restart.

  1. What is the acceleration of the ball for each region (the lowest flat surface, the hill, and the highest flat surface)?
  2. When the ball is on the hill, would you say that the velocity of the ball is increasing, decreasing, or constant?  What about its speed?
  3. Suppose you want to putt the ball so that it just barely makes it to the hole at the top of the hill.  What should the initial velocity of the ball be (i.e., the velocity of the ball at the bottom of the hill)?
