Maximizing Area with a Projectile 2

A projectile is fired from a height h h , as shown in the figure, with an initial velocity v v at an angle of inclination θ \theta from the horizontal. Determine θ \theta in degrees so that the area A A under the trajectory is a maximum.

Details and Assumptions

  • 3 v 2 = g h 3v^2=gh .
  • Neglect air resistance.
