A rescue plane flies at an altitude of 400m above the ground. The plane is traveling with a constant vertical speed of 300km/h. A package is released 300m before the target.
(i) What vertical velocity should the package be given so that it arrives precisely at the target?
(ii) At what angle will the package hit its target?
