Cannon Ball 2 !!!

Two friends Robert and Alex are playing a cannonball game. Each of them is provided with an identical steel ball of the same mass and volume (they just differ in color). They are having a competition to see who can launch their ball the farthest. The only difference between them is that Robert fires his ball at an angle of θ\theta whereas Alex fires his ball at an angle of θ"=(90θ)\theta^" = (90^\circ - \theta).

Can you predict who will be the winner of the game?

Details and Assumptions:

  • Assume no wind is blowing and neglect air resistance.
  • The horizontal displacement of a body from its point of projection to its final destination is known as the range.
