The center field fence in a ballpark is 10ft high and 400 ft away from home plate. The ball is hit 3 feet above the ground. It leaves the bat at an angle of θ degrees with the horizontal speed of 100 miles per hour.

A) write a set of parametric equations for the path of the ball.

B) graph the path of the ball when θ = 15 Is the hit a home run?

C) find the minimum angle at which the ball must leave the bat in order for the hit to be a home run.
