the relative velocity of ball wrt ground is (u-v)


it will go up a distance of (u-v)^2/2*g


and then come to the same height after a time period of (u-v)/g


during this time interval the balloon would be at -(u-v)v/g


now take the rest of the time to be t


during this time the ball comes down a distance of (u-v)v/g + vt


put this distnace into -gt^2/2


a quadriatic equation in t would come solve it for a positve t


now add t with (u-v)/g


this will be the answer
