Two football players kicked the ball from opposite ends of the field which is 100 m long. Player
A kicked the ball with the initial velocity vA0 so that the ball reaches maximum distance. Player B however
kicked with twice the initial velocity of that of player A. Both players kicked the ball simultaneously and both
balls hit the ground at the same time. What is the initial velocity (both magnitude and direction), total time of
flight, and the maximum height that the ball reached in each case?
