A stone released from balloon moving upwards with some constant velocity, the initial velocity of stone is same as the velocity of balloon with opposite sign, but how? What i thought is that the instant stone is released which goes upwards with balloon, stone which is going upwards would stop (t=0) velocity (u=0).

So you're saying that there's NO difference between just releasing the stone from a stationary balloon that isn't moving? Think again.

No, not opposite sign. Same sign.

You're free to think whatever you want. That doesn't make it right.

Think about that for a moment. When you throw a stone upwards, you release it from your hand while your hand is moving upwards rapidly... What happens?
