Paragraph

A gun crew observes a remotely controlled balloon launching an instrumented spy package in enemy territory. When first noticed the balloon is at an altitude of 800 m and moving vertically upward at a constant velocity of 5 m/s. It is 1600 m down range. Shells fired from the gun have an initial velocity of 400 m/s at angle 37° from horizontal. The gun crew waits and fires so as to destroy the balloon . Neglect air resistance. The altitude of collision in meter is :-
