Problem 2.5

Animation 1 Animation 2

Please wait for the animation to completely load.

Observe the two animations (position is given in meters and time is given in seconds)Restart.

  1. Sketch the velocity as a function of time for each animation.  Draw both functions on the same graph in order to compare the two animations.
  2. Make a second velocity vs. time sketch for Animation 1.  On your graph, make sure to have a long enough time interval that the ball's position is between x = -2 m and x = 2 m twice.  What is the area under this portion of the velocity curve?  Remember the convention that area under a curve above the axis is considered positive and area below the axis is considered negative.  How would your answer change if you did this for Animation 2?
