The parametric equations for the path of a projectile launched at a height h feet above the ground, at an angle
with the horizontal and having an initial velocity of
feet per second is given by
and
. The center field fence in a ballpark is 10 feet high and 400 feet from home plate. The ball is hit 2 feet above the ground. It leaves the bat at an angle of
degrees with the horizontal at a speed of 110 miles per hour as shown in the figure. Write a set of parametric equations for the path of the ball.
