  Below is the bounce ball expression, how can i easy ease keyframes at the end ?

  Expression:

  e = .9;
  g = 3000;
  nMax = 5;

  n = 0;
  if (numKeys > 0){
  n = nearestKey(time).index;
  if (key(n).time > time) n–;
  }
  if (n > 0){
  t = time – key(n).time;
  v = -velocityAtTime(key(n).time – .001)*e;
  vl = length(v);
  if (value instanceof Array){
  vu = (vl > 0) ? normalize(v) : [0,0,0];
  }else{
  vu = (v < 0) ? -1 : 1;
  }
  tCur = 0;
  segDur = 2*vl/g;
  tNext = segDur;
  nb = 1; // number of bounces
  while (tNext < t && nb <= nMax){
  vl *= e;
  segDur *= e;
  tCur = tNext;
  tNext += segDur;
  nb++
  }
  if(nb <= nMax){
  delta = t – tCur;
  value + vu*delta*(vl – g*delta/2);
  }else{
  value
  }
  }else
  value
