Problem 2.9

Please wait for the animation to completely load.

The animation simulates the motion of a helium balloon with the effect of air resistance neglected.  A graph of y velocity vs. time for the balloon is also shown (position is given in meters and time is given in seconds).   Restart.

1. Is the y velocity increasing, decreasing, or constant?
2. Is the y acceleration increasing, decreasing, or constant?
3. What is the acceleration of the balloon?
