heavy and light P1 mp4

Hi all,Here is my third bouncing ball exercise to improve in timing and spacing,After researching references to start with the animation,i saw one particular image of light and heavy ball time chart which had a barrier in the middle,i decided to go with the same setting in the time chart...but i had to tweak the time in some places i thought its needed,but the image really helped me to understand what im about to do and helped me through the animation.I will still try to trace the image to its source so i can acknowledge the person who saved my life in animating a heavy and light ball so easily that i spent little time animating it and i learnt lot of things
