A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 19.3m/s A 1.0-kg stone is thrown from the basket by an initial velocity of 12.1m/s perpendicular to the path of the descending balloon, as gauged relative to a person at rest in the basket. The person in the basket sees the stone hit the ground 5.10s after being thrown. Presume that the balloon continues its downward descent by the same constant speed of 19.3m/s.
1) How high is the balloon when the rock hits the ground?
2) At the instant the rock hits the ground, how far is it from the basket?
3) Just before the rock hits the ground, discover its horizontal and vertical velocity components as measured by an observer at rest in the basket.
4) Just before the rock hits the ground, discover its horizontal and vertical velocity components as measured by an observer at rest on the ground.
