A plane with supplies is at an altitude h a distance over ground x from its drop point and the nose makes an angle tex2html_wrap_inline34 below horizontal.

a.
What speed must the plane have at that moment to be able to release its supplies and have them land right on the drop zone?
b.
When does this equation blow up (what are the limits of the variables)? Why?
Ignore air resistance and consider tex2html_wrap_inline34 to be the direction of the velocity of the plane.
