Hehe...this wasn't as easy as it first sounded but here's one solution:
Code:
if (time == 0)
{
//initialize
Coin.rotateY = 0;
}
else if (time < 3)
{
// accelerate to 3 secs of time
Coin.rotateY = Coin.rotateY + time * 10;
}
else if (time < 6)
{
// maintain constant speed while time is less than 6 secs
Coin.rotateY = Coin.rotateY + 30;
}
else if (time >= 6 && time < 9)
{
// decelerate back to zero speed between 6 and 9 secs
Coin.rotateY = Coin.rotateY + 30 - 10 * (time - 6);
}
//this is just to prevent overflows
while (Coin.rotateY > 360)
Coin.rotateY = Coin.rotateY - 360;
the deceleration equation might seem like a quick hack but it has a purpose if you think it over. I'll leave it to you to figure it out 
Feel free to ask, if you don't understand...
