Answer:
Let \[\upsilon \] be the velocity of
ball at an instant, when it makes an angle P with the horizontal. The
horizontal component velocity of the ball = \[\upsilon \cos \beta \].
Initial horizontal
component velocity of ball = \[u\cos \alpha \]
In angular
projection of a projectile, the horizontal component velocity remains
unchanged, hence
\[\upsilon \cos
\beta =u\cos \alpha \] or \[\upsilon =u\cos \alpha
/\cos \beta \]
