Puppet pin damped amplitude

Hi everyone
I like to make an animation of a a pingpong ball bouncing along a table ending by laying still with no movement. Off cause i can do it frame by frame, but I bet it can be done smarter. I guess it is a damped sinus function im looking after. Also a damped wiggle expression could be nice. I thought i could use the aplitude argument, bu so far I had no luck. 
Any sugestions? Thanks in advance
