**urgent problem acceleration force vs. gravity**

Sorry if this is the wrong forum.

I got a problem in my last physics class I am having some trouble with.

A balloon goes straight up with 15m/sec.

After the balloon went up 2m sb. drops a compass.

But the balloon still goes up and doesn't stop.

So the question is when (time) does the compass hit the bottom.

So you probably need to have a equation with the acceleration force of the rising balloon and the gravity (9.8m/square second).

Hope somebody can help me.

Thank you very much.
