A rescue plane wants to drop supplies to isolated mountainclimbers on a rocky ridge 235 m below. If the plane is travelinghorizontally with a speed of 189 km/h (52.5 m/s ), how far inadvance of the recipients (horizontal distance) must the goods bedropped? Suppose, instead, that the plane releases the supplies ahorizontal distance of 425 m in advance of the mountain climbers.What vertical velocity (up or down) should the supplies be given sothat they arrive precisely at the climbers' position?
