Hi,

I was watching a hot air balloon show, and one of the demonstrations was someone dropping a ball out of a rising hot air balloon. If a hot air balloon is rising at let's say 19.6m/s, and you drop a ball directly down, will the ball continue to rise for two seconds because it has an intial velocity of 19.6 m/s before the ball starts to fall?

Yes.

The ball begins to decelerate immediately (under gravity) and therefore, from the point of view of the balloon observer, the ball will fall away from the balloon as soon as it is let go.

However, from the point of view of the ground observer, the ball's velocity remains positive (although decreasing) for 2 seconds before it begins to descend.
