A rescue plane wants to drop supplies to isolated mountain climbers on a rocky ridge 235 m below. Assume the plane is traveling horizontally with a speed of 260 km/h (72.2 m/s).
(a) How far in advance of the recipients (horizontal distance) must the goods be dropped (in meters)?
m
(b) Suppose, instead, that the plane releases the supplies a horizontal distance of 425 m in advance of the mountain climbers. What vertical velocity (up or down) should the supplies be given so that they arrive precisely at the climbers' position (in m/s) (Assume up is positive.)
(c) With what speed do the supplies land in the latter case?
(in m/s)
