2.A hot air balloon starting on the ground ascends at a rate of 12 km/hr and is carried by the wind (horizontally) at a rate of 20 kn/h. When the balloon reaches a height of 50 m, a ballast bag is dropped. Where does the ballast bag land relative to the starting location of the balloon? What is the speed of the ballast bag when it lands?
