A 124 kilogram balloon carrying a 22 kilogram basket is descending with a constant downward velocity of 18.8 m/s. A 1.0 kilogram stone is thrown from the basket with an initial velocity of 12.3 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 7.50 second after being thrown. Suppose that the balloon continues its downward descent with the same constant speed of 18.8 m/s.
Part A Determine how high was the balloon when the rock was thrown out?
Part B Find how high is the balloon when the rock hits the ground?
Part C At the instant the rock hits the ground; calculate how far it is from the basket?
Parts D Just before the rock hits the ground, obtain its horizontal and vertical velocity components as measured by an observer at rest in the basket.
Part E Just before the rock hits the ground, obtain its horizontal and vertical velocity components as measured by an observer at rest on the ground.
