A cannon ball is projected so as to attain a maximum range. Find the maximum height attained if the initial velocity is U.

Answer 1

π/4 is the launch angle for maximum range on a level surface

the vertical component of the launch velocity would be ... U √2 / 2

kinetic energy at launch is potential energy at peak ... U^2 / 4 = g h

solve for h
