We are given horizontal range of ball. We are also given time of flight for the ball.
The time of flight is given as
Here are initial velocity and angle of projection respectively.
The range is the horizontal component of velocity times the time of flight. We hence obtain 2 equations of motion which we solve simultaneously to find velocity and angle.
