A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 25.2 m/s A 1.0-kg stone is thrown from the basket with an initial velocity of 11.7 m/s perpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. The person in the basket sees the stone hit the ground 6.70 s after being thrown. Assume that the balloon continues its downward descent with the same constant speed of 25.2 m/s .
