Alex hits the baseball at a 28° angle with an initial velocity of 103 feet per second.  The ball is 4 feet off the ground (initial height) at time of impact.  The ball is not caught by the outfielder and hits the ground.  How far from home plate is the ball, approximately? (Round to the 3 decimal places)
