A 2.00 m tall basketball player makes a three point shot from the three point line, which is 7.24 m along the floor from the hoop, which is 3.00 m above the floor. The player threw the ball with an initial speed of 9.00( m)/(s) at an angle of \theta
= 48.8\deg relative to the horizontal. Taking the x axis to be parallel to the floor and the origin to be at the player's feet, what is the x coordinate of the ball at the moment that it reaches its maximum height?
