What is the change in momentum between the initial and final points of the projectile path, if the range is maximum?

The initial velocity of the particle during the point of projection is given as:ui = u cosθ i^ + u sinθ j^velocity at the final poin when the body reaches the ground = uf = u cosθ i^ - u sinθ j^change in velocityu = uf - ui u =u cosθ i^ - u sinθ j^ - u cosθ i^ + u sinθ j^u =-2 u sinθ j^for maximum range θ = 45ou =-2 u sin45 j^u = -22u  j^u = 2  uTherefore change in momentum p = 2u ×m
