A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of A 1.0-kg stone is thrown from the basket with an initial velocity of 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 6.00 s after being thrown. Assume that the balloon continues its downward descent with the same constant speed of
(a) How high was the balloon when the rock was thrown out?
(b) How high is the balloon when the rock hits the ground?
(c) At the instant the rock hits the ground, how far is it from the basket?
(d) Just before the rock hits the ground, ?nd its horizontal and vertical velocity components as measured by an observer
(i) at rest in the basket and
(ii) at rest on the ground.
